Getting the above error trying to test a pipeline, but it's pretty generic. Any recommendations how to troubleshoot?

Start by reproducing the failure with `elastic-package test pipeline -v` and `-g`, then inspect the pipeline content and the marshalling path implicated by the `map[interface {}]interface {}` error. Done means the affected pipeline test runs successfully and the failure has regression coverage or a clearly actionable diagnostic.
