Failed validating 'type' in schema['properties']['fields__resolution']

[akoebbe-uu]

I'm very new to Meltano so please forgive me if this is an obvious mistake. I'm getting the following error when doing an elt from Jira (meltanolab) to a Postgres target.

FWIW it does not error out when flattening is disabled.
