My code, which used to work until yesterday, suddenly stopped working. I'd been running codes from jupyter notebook to auto-collect repeating data from a webpage. It is as follows (URL is changed to Google for privacy reasons):
# use selenium to start Chrome session to open a certain page
dr = webdriver.Chrome()
dr.get("http://www.google.com")
The error message I got:
---------------------------------------------------------------------------

I really have no idea how to solve this and why I'm suddenly getting this message.
Download again new chrome driver from below link and use the same

I am trying to run sample codes using selenium and webdriver manager from the following site: https://pypi.org/project/webdriver-manager/. I am using google chrome, i tried the following codes:
Selenium version: 4.1.0
webdriver_manager version: 3.5.2
# code for chrome
# Selenium 4
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()))
I also tried:
# code for chromium

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager
from webdriver_manager.utils import ChromeType
driver = webdriver.Chrome(service=Service(ChromeDriverManager(chrome_type=ChromeType.CHROMIUM).install()))
Unfortunately i get the following error (it's similar for both codes):

I am using pyspark in databricks to append data to a sql table via ADF pipelines. Code is sown below:
log_status_df_all = spark.createDataFrame(log_status_df_all)
log_status_df_all.write.format("com.microsoft.sqlserver.jdbc.spark").mode(write_mode).option("url", url).option("dbtable", 'Logs_Collection_Status').option("user", username).option("password", password).save()
log_status_df_all.show()
On some days I am get the error message:
com.microsoft.sqlserver.jdbc.SQLServerException: There is already an object named '<table_name>' in the database.
Upon simply re-running the pipeline the table is updated with no issues; therefore the code is working. How can I prevent this from happening again? Is it an error when multiple pipelines try writing to the same table at the same time?
The rest of the error message is shown below:

The issue has now been resolved.
Previous code:
if condition1==True:
write_mode = 'overwrite'
elif condition2==True:
write_mode = 'append'
log_status_df_all = spark.createDataFrame(log_status_df_all)

log_status_df_all.show()
Current code:
write_mode = 'append'
log_status_df_all = spark.createDataFrame(log_status_df_all)
log_status_df_all.write.format("com.microsoft.sqlserver.jdbc.spark").mode(write_mode).option("url", url).option("dbtable", 'Logs_Collection_Status').option("user", username).option("password", password).save()
