Encountering the SessionNotCreatedException error: Unable to initiate a new session. Response code 500 within the Azure pipeline

After setting up a pipeline in Azure-Devops and configuring a self-hosted agent for the same, I encountered an issue where it opens the browser but fails with a sessionNotCreatedException.

Interestingly, when running the same code using STS or eclipse tool, it runs successfully without any errors.

The error message faced is as follows: org.openqa.selenium.SessionNotCreatedException: Could not start a new session. Response code 500. Message: session not created: Microsoft Edge failed to start: exited normally. (session not created: DevToolsActivePort file doesn't exist) (The process started from msedge location C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe is no longer running, so msedgedriver is assuming that msedge has crashed.)

Answer №1

If you're facing a problem, here are some steps you can try to resolve it:

  1. Add the following arguments to the Edge options in your code:

    • --remote-debugging-port=<port>
    • --headless

  2. Ensure that you specify the correct path for msedgedriver. For example:

    self.driver = webdriver.Edge(executable_path='path/to/msedgedriver')

  3. You may have multiple Edge Driver copies running. Search for any redundant Edge Drivers using keywords like "msedgedriver" or "MicrosoftWebDriver" and delete older versions.

  4. To prevent data loss, create a backup of your User Data folder in a new directory before running selenium tests.
