I installed pgadmin4 (v4.4) package with from official Arch Linux package repository. It worked until the most recent update. Now I am not able to add a new server. In the browser I got the error:
http://127.0.0.1:36699/browser/server_group/children/1 500 (INTERNAL SERVER ERROR)
And from the server log, I got the error:
2019-04-09 21:41:49,900: ERROR flask.app: 'psycopg2.extensions.Column' object has no attribute '_asdict'

I wonder if whether it is only me because I didn't get anything from google search.
I have the same issue psycopg2 2.8.1. Downgrade to 2.7.7 makes the trick.
pgAdmin4 team has released the new version pgadmin4 (v4.5) which will work with latest version of psycopg2 which is psycopg2 2.8.1
https://www.pgadmin.org/download/
Bug: https://redmine.postgresql.org/issues/4143
In my case, first attempt of execution of command /usr/pgadmin4/bin/setup-web.sh showed below error that caused the web URL to show 500 error.
/usr/pgadmin4/bin/setup-web.sh: line 87: semanage: command not found
I'm using AlamLinux. I installed the required package and ran setup-web.sh again to make the web URL working
yum install policycoreutils-python-utils
/usr/pgadmin4/bin/setup-web.sh

When I run my code it crashes please help and this was made late at night so I may have missed something obv. Instead of launching chrome driver like my other programs Ive made it runs actual chrome. is there a fix?

This error:

is basically you do not have compatible version of browser and browser driver.
as of 29th-Aug-2021
Latest stable release: ChromeDriver 92.0.4515.107
and Google chrome browser version is Version 92.0.4515.159 (Official Build) (64-bit)
Download link for chromedriver, try to get 92.0, and that should help you past this issue.
I want to create a program in pythonista that can control the web browser. I know Selenium is the best for this but I have tried it on pythonista for my iOS iPhone and I get an error.
This is the code:
from selenium import webdriver
browser = webdriver.Chrome()
browser.get('http://www.yahoo.com')
Here is the error:
PermissionError: [Errno 1] Operation not permitted

...implies that the ChromeDriver was unable to create a desired new resource e.g. logfile while initializing a new WebDriver and Web Client session.
As per the discussion Pythonista - Limitations due to iOS following are some of the limitations while using Pythonista :
No fork/exec for new processes. Impacts the subprocess module.
Due to missing fork, no full cleanup of process resources (memory, threads, file handles).
No file access outside of application directory.
No /dev/null and other special files.
Limited processing power of devices (compared to typical PC/Mac).
Process usually is stopped/killed after a while.
An simple example is as follows :
>>> import subprocess
>>> subprocess.call(["ls", "-l"])

What's wrong in your usecase
There can be 2 issues as follows :
When you invoke the following line of code :
browser = webdriver.Chrome()
The ChromeDriver tries to create/modify/access the scoped_directory within the file system. For example on Windows OS :
"chromedriverVersion": "2.35.528161 (5b82f2d2aae0ca24b877009200ced9065a772e73)",
"userDataDir": "C:\\Users\\username\\AppData\\Local\\Temp\\scoped_dir5188_12717"
Possibly ChromeDriver is unable to perform this task/method/functionality.
Again when you invoke the following line of code :
browser = webdriver.Chrome()
As per selenium.webdriver.chrome.webdriver ChromeDriver tries to create a logfile within the file system as per the constructor as follows :
class selenium.webdriver.chrome.webdriver.WebDriver(executable_path='chromedriver', port=0, options=None, service_args=None, desired_capabilities=None, service_log_path=None, chrome_options=None)
Possibly ChromeDriver is unable to perform this task/method/functionality,
Due to the above mentioned reasons you are seeing the error :
PermissionError: [Errno 1] Operation not permitted
Solution
Incase of any of the above mentioned cases the solution would be to restrict the access/creation of the resources within the application directory only.

I use TF1.7.0 instead of TF0.12.1, and fix this problem. But I still don't know what happen in TF0.12.1.
In this question I am not asking to help solve this problem (that would be too much asked). I am asking where I can find the code that actually generated that error message.
The error massage occurs when running with a firefox webdriver with python-selenium.
As far as I know the first part
WebDriverException: Message:
is generated by selenium itself. But where does the other part come from?
TypeError: rootNode is null
Is it from firefox itself? geckodriver? Marionette? Something else?
What source code do I need to check to find the following character string?
TypeError: rootNode is null

exceptions.IOError: [Errno 22] invalid mode ('r+') or filename: 'E:\\master_dir\\http.log'
I found that my http.log has reached a size of 4GB although it should rotate after 10MB. Why the buildbot was not able to rotate the http.log after 10MB? Why I am getting the error Invalid mode (r+)? Is there a build config parameter to set the rotate size for http.log?
Deleting the file atleast solved the problem of starting buildmaster but I am still clueless why I got this error at the very first place.
I am running buildbot version 0.8.8
Thanks.
EDIT
As asked by djmitche, I tried with twisted logging module. It was logging fine, irrespective of the order of slashes.
######## TWISTED ##########
from twisted.python.logfile import LogFile
LOG_FILENAME_TWISTED = r'C:\wp\log_rotate_twisted.log'
lf = LogFile.fromFullPath(LOG_FILENAME_TWISTED, rotateLength=20)
# Log some messages
for i in range(20):
lf.write('i = %d' % i)
This may be an issue with Twisted Python (and I've proposed adding the corresponding tag).
Can you verify that the log rotation parameters are set correctly, perhaps by patching C:\Python27\lib\site-packages\buildbot-0.8.8-py2.7.egg\buildbot\status\web\baseweb.py in _openLogFile to print rotateLength? The printed output will appear in twistd.log when you restart the master.
