When you are not experienced on the platform you are building on, all debugging is heroic.
It's really strange that they would invest all this time as if they are keen to understand the cause of why it happened, but then be satisfied when jiggling the handle solved it. The real cause ultimately is a process one (developer discipline) or a pipeline one (bad build/test/deployment processes). They got close to realizing it and then blamed the language instead of what appears to be bad practices happening on their dev team.
