URL has expired Device Farm AWS


I was unable to find a solution to this error, I run selenium test with pytest to aws device farm and sometimes this error appears, making the test unstable. Could someone please care to explain why this happens and sometimes it doesn't? I haven't been able to find anything about it.

E selenium.common.exceptions.WebDriverException: Message: URL has expired


Solution

  • When you create a remote URL for accessing selenium sessions on AWS Device Farm, you specify when that URL expires. If you specify a value too low, the URL will expire during your test, resulting in a URL has expired message.

    For more information, look at the CreateTestGridUrl documentation and view the expiresInSeconds parameter.
