The dscc and/or istool command can be used to help debug this and isolate the error. Connect to the Agent Host machine (the one where your build agent (e.g. Jenkins Agent, ADO Agent, Gitlab runner, or Bamboo Remote Agent) is running), open a Command Prompt, then try to use istool to export an ISX of a job you saw a failure for, and/or try to use dscc to compile one of the jobs you observed failing. You must do this in the project that was failing, using the same userid and credentials your build agent uses, or it is not an accurate test. Capture the full log of this test for further analysis. If either or both commands fail the same way from the command line, you have ruled out MettleCI, as this isn’t a MettleCI issue. The error is being reported by istool or dscc and simply captured by MettleCI logging. If both istool and dscc succeed in an identical environment when the CLI fails, then contact MettleCI support.
