non-harvest-blocking error message: Registry displays a "something went wrong" message when triggering "harvest" & "publication" tasks; task runs through to Airflow

[christinklez]

From the Registry:

• Either "harvest" or "publish staged" collection(s) from the Registry.
• An error message will appear at the top banner of the Registry, when the page reloads.
• But if you go to Airflow, the job is actually running.
