    XMLWordPrintable

Details

    Description

      We are seeing an intermittent issue where the first job running on a newly provisioned Windows EC2 agent fails to complete the automatic default checkout in the pipeline. The error shows there is an issue with the credentials being injected:

      This looks to me like the variable containing the location of the SSH key file is empty.

       

      As it is only intermittent, I thought it might be a timing issue but adjusting all available startup delays and timeouts has not helped.

       

      Any idea or advice on how to diagnose what's going on here would be appreciated.

          This looks to me like the variable containing the location of the SSH key file is empty.

           

          As it is only intermittent, I thought it might be a timing issue but adjusting all available startup delays and timeouts has not helped.

           

          Any idea or advice on how to diagnose what's going on here would be appreciated.
