From the log file you have sent; you are getting the same output code (R027) but it doesn’t seem it’s the same issue.
Michael’s issue related to not seeing enough logging to understand where Cover couldn’t create Spring context, and what beans were missing.
From your log file we do see a partial test which should show us where Cover struggled to find the Spring context.
I can see you have created a different thread here with the same log file attached - we can have a look there, and get back to you on that thread.
Kind regards,
