Running a GAP background job does not return a result

[vfxcode]

When we run a Map Analysis from two Standards we get the following error in the logs:

INFO:application.database.db:looking for gap analysis with cache key: Standard1 >> Standard2
INFO:application.database.db:found gap analysis with cache key: Standard1 >> Standard2
ERROR:application.web.web_main:Finished job does not have a result object, this is a bug!

The worker seems to print the following:
