Object Null Reference On Every command

[Ali Khakpouri]

This is BitBucket Server product.

In every command (i.e. clone, pull, push, merge, etc), I'm presented with the "NullReferenceException encountered. Object reference not set to an instance of an object." exception.

When looking at the logs in C:\Atlassian\ApplicationData\Bitbucket\log, I see the followings:
