The developer ended up determining that it’s not the specific version of his software that is doing it. It’s tied to pytest-cov instead which is the same version in all of my past passing builds and failing new ones. Forcing coverage==5.0.1 proved to be just a red herring after-all.
He also made an observation that it is tied to an alpha version of SQLite (5.0a2) that is installed. This kind of hints that the container has changed from the past (and to now). Is there anyway we can roll back from the alpha build and use the previous stable version instead?
Perhaps you have some suggestions?
