OSError: [Errno 5] Input/output error

[uranusjr]

Hmm, this very much looks like a Flask-Appbuilder bug. Unfortunately the last four stacks (the rich part) is masking the real error here, it raises an exception when trying to write the actual error. Not sure if there’s a way to disable Rich so we can get the actual problem.

[uranusjr]

@willmcgugan Do you happen to know what would cause the OSError: [Errno 5] Input/output error exception to be reached so maybe we can fix that first?

[eladkal]

Is this still happens in main version? We upgraded flask versions. @nediGit can you please check?
