This appears to be coming from the resumable decorator docstring
https://github.com/VisionSystemsInc/terra/blob/55b1ce95705be6bc75f3008879e7e6b4f5a8458e/terra/utils/workflow.py#L43-L46

Maybe the following would fix it (calling out the full exception path)?

  Raises
  ------
  terra.utils.workflow.AlreadyRunException
      Thrown when function attempts to run a second time.
