Error Handling

• Error: Skipping run due to missing attribute(s).

  • A Run is missing a timestamp for a status. Normally caused by Runs stuck in Pending state, which should be discarded if they aren’t meant to complete, successfully or otherwise.

• Error: One or more Python exceptions.

  • Multiple possible causes. One of the most common is due to the script hitting the Terraform Cloud API rate limit (30 requests per second). There is a safeguard that slows down execution to avoid this.
