I am receiving following error while executing the line(selenium chrome driver):
driver.findElements(By.className("myClass"));
unknown error: unhandled inspector error: {"code":-32000,"message":"Cannot find execution context with given id"}
What is the reason for this error? How can i solve it?
I had this issue today exclusively with ChromeDriver on a project that has been working fine. I found that upgrading to the following version of ChromeDriver fixed the issue for me:
ChromeDriver v2.21 Download Page
Apparently it is due to a bug. See:
https://bugs.chromium.org/p/chromedriver/issues/detail?id=1238
for more information.
I had the same problem. It disappeared after upgrading to version 2.21:
http://chromedriver.storage.googleapis.com/index.html?path=2.21/
The problem also affected me when I was trying to click on an element which was in the default content and I was on an iFrame.
Adding the following code solved it for me:
driver.switchTo().defaultContent();
Had this issue it's due to being on the wrong frame. Switch back to the root frame (Default Frame) and you'll be fine

I'm at Phalcon 5.0 and I am having issues calling camelize. I reached out to the community and was told that they will fix the help links that goes to 404.
Here's my issue:
$options['className'] = Text::camelize($options['name']);
is throwing error:
Fatal error: Uncaught Error: Class 'Phalcon\Builder\Text' not found
Long shot since I've never used Camelize, but in the 5.0 changelog there is a reference to Phalcon\Support\Helper\Str\Camelize. I'm wondering if they moved where Camelize lives?
Again... total guess on my part...
During work on my kotlin project using InteliJ IDE suddenly I get following error
Exception in thread "main" java.lang.NoClassDefFoundError: kotlin/jvm/internal/Intrinsics
at com.beust.klaxon.DefaultConverter.(DefaultConverter.kt)
My old code which compile without problems now throw this exception. How to fix it?
I don't know what is the reason - but this helps: reload gradle by click on
After that error disappear. I hope someone give explanation in separate answer
This question already has an answer here:
Unable to import org.openqa.selenium.WebDriver using Selenium and Java 11

Closed 3 years ago.
I'm getting the following error :
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
WebDriver cannot be resolved to a type. ChromeDriver cannot be resolved to a type at firstproject/firstprojetone.MyLatestClass.main(MyLatestClass.java:14)
I have Installed Java 11.0.2 version, Ecllipse IDE 2018-12(64 Bit) and Lib and Configured with ecllipse IDE.
Java programs are executing successfully.
In general, in case of any problems with your import or package name, it results in the exception. Deletion of the package name or fixing import errors might help resolving the issue.
The problem may be even clear, if you can share your code
Exception in thread "main" java.lang.Error: Unresolved compilation problems: WebDriver cannot be resolved to a type.
You need to add selenium webdriver jar files to the project to get rid of that
right click on project-->goto build path-->configure build path-->click on "Add external jars"-->add selenium jar files from your local machine-->click ok-->now mouseover on WebDriver in your code-->click "import webdriver"--now run your code-->you will get rid of the exception.
After adding your jar you need to do some modification as per your comments i found, you write
driver.get("google.com");
and it will throw error invalid URL. you need to use below syntax.
driver.get("https://www.google.com");
Hope this helps.
I'm trying to make an automated test for my webpage and I'm using Jasmine in tandem with selenium.
When testing on chrome (using chromedriver) I get, unpredictably, the error below. It happens frequently enough that when I run a test suite it hardly ever finishes.
Ive found evidence of this bug but cant find a solid answer: https://bugs.chromium.org/p/chromedriver/issues/detail?id=732 (granted this was for chromium and I'm using chrome)

We've also been struggling with this issue for a long time now and recently resolved it so thought I would post here incase it helps someone else.
Turns out for us it was memory related. We run our tests inside a docker container and the docker default dev/shm size is 64mb. Increasing this resolved the "no such session" issue for us.
We use docker compose so just added shm_size: 256M to the docker-compose.yml file.
I recently encountered this exception too. It first appeared to be undeterministic too, but after thorough investigation I realized that it happens deterministrically if you call ChromeDriver.Close() and then tries to FindElement.
In my case, ChromeDriver.Close() was called in an exception handler of a previous test, which happened due to a timing issue. This only affected the next test so it added to the feeling that this issue is flaky. But as I said, my investigation revealed that it is deterministic.
Having said that, this is my experience with that error. Could be that your case is different...
This error message...
WebDriverError: no such session
(Driver info: chromedriver=a.b.c (36d3d07f660ff2bc1bf28a75d1cdabed0983e7c4),platform=Mac OS X 10.11.5 x86_64)
...implies that the ChromeDriver was unable to communicate with the existing Browsing Context i.e. Chrome Browser session.
We have discussed and analyzed this issue within the discussion Issue 732: No such session error - inconsistent problem which appears when running tests for a prolonged period. This error is usually observed after an extended period of executing the Test Suite as follows:
[0127/105308:ERROR:nacl_helper_linux.cc(289)] NaCl helper process running without a sandbox!
Most likely you need to configure your SUID sandbox correctly
[489.849][INFO]: RESPONSE FindElements unknown error: session deleted because of page crash
from tab crashed
(Session info: chrome=p.q.r.s)
[489.849][DEBUG]: Log type 'driver' lost 0 entries on destruction
[489.849][DEBUG]: Log type 'browser' lost 9 entries on destruction
This error is defined in nacl_helper_linux.cc as follows:
// If the Zygote has started handling requests, we should be sandboxed via
// the setuid sandbox.
if (!IsSandboxed()) {
LOG(ERROR) << "NaCl helper process running without a sandbox!\n"
<< "Most likely you need to configure your SUID sandbox "
<< "correctly";
Precisely the FindElement(s) method have FAILED due to sandbox issue and Page Crash occured due to session deletion
Solution
This error can happen due to a lot of diverse reasons and the solution to address this error are as follows:
Initiate the Chrome session configuring ChromeDriver with the argument --disable-impl-side-painting
Additionally, you can also add the argument --enable-gpu-rasterization which allow heuristics to determine when a layer tile should be drawn with the Skia GPU backend. Only valid with GPU accelerated compositing + impl-side painting.
As an option, you can also add the argument --force-gpu-rasterization which always uses the Skia GPU backend for drawing layer tiles. Only valid with GPU accelerated compositing + impl-side painting. Overrides the kEnableGpuRasterization flag.
This error is also observed when the server does not recognize the unique session identifier. This happens if the session has been deleted or if the session ID is invalid in either of the following ways:
Explicit session deletion: A WebDriver session is explicitly deleted when explicitly invoking the quit() method as follows:
from selenium import webdriver
from selenium.common.exceptions import InvalidSessionIdException
driver = webdriver.Chrome(executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
print("Current session is {}".format(driver.session_id))
driver.quit()
try:
driver.get("https://www.google.com/")
except Exception as e:
print(e.message)
#Console Output:
Current session is a9272550-c4e5-450f-883d-553d337eed48
No active session with ID a9272550-c4e5-450f-883d-553d337eed48
Implicit session deletion: A WebDriver session is implicitly deleted when you close the last window or tab invoking close() method as follows:
driver = webdriver.Chrome(executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
print("Current session is {}".format(driver.session_id))
# closes current window/tab
driver.close()
try:
driver.get("https://www.google.com/")
except Exception as e:
print(e.message)
#Console Output:
Current session is a9272550-c4e5-450f-883d-553d337eed48
No active session with ID a9272550-c4e5-450f-883d-553d337eed48
You may also have to add the argument --no-sandbox
Chrome seem to crash often in Docker containers on certain pages due to too small /dev/shm. Similarly, you may have to fix the small /dev/shm size.
An example:
sudo mount -t tmpfs -o rw,nosuid,nodev,noexec,relatime,size=512M tmpfs /dev/shm
It also works if you use -v /dev/shm:/dev/shm option to share host /dev/shm
Another way to make it work would be to add the chrome_options as --disable-dev-shm-usage. This will force Chrome to use the /tmp directory instead. This may slow down the execution though since disk will be used instead of memory.
chrome_options.add_argument('--disable-dev-shm-usage')
Reference
You can find a couple of detailed discussions in:
selenium.common.exceptions.WebDriverException: Message: invalid session id using Selenium with ChromeDriver and Chrome through Python
unknown error: session deleted because of page crash from unknown error: cannot determine loading status from tab crashed with ChromeDriver Selenium
org.openqa.selenium.SessionNotCreatedException: session not created exception from tab crashed error when executing from Jenkins CI server
Sometimes we just expect any problem to be very complex and are looking for its cause far too deep, when a problem could be so obvious.
I was seeing this issue when I explicitly called browser.close() as an exception handler in my logout() method. It terminated the session and all of the following protractor tests were throwing this error.
Once I removed browser.close() and just threw an error instead, the problem was solved.
With Selenium RC 1.0.1, and FF3.5.x or 3.6 I keep seeing this error when trying to run any test,
Failed to start new browser session:
Unable to delete file
\parent.lock
when running the server with either,
java -jar selenium-server.jar -multiwindow
or
java -jar selenium-server.jar
Any one found a way to run a selenium RC test against those version of FF? Here's the full stack trace,

Restarting the browser, and clearing the cache didn't help. Using FF 3.0.x works just fine.
Seems seleniumRC 1.0.2 just came out today with claimed support for FF3.6 and such. Is working for me.
I was able to fix this issue by following these instructions:
http://jira.openqa.org/browse/SRC-507
This is for an older version of Selenium, but it works just the same. I am having to use 1.0.1 (for IE compatibility) and it has the MaxVersion of FF at 3.5. It was throwing the same error as above.
I changed the various files to '3.6' and it works now.
I just downloaded Selenium RC 1.0.3, and it did NOT fix the problem for me.
