Between me and my co-worker we were setting up a git repo. Nothing fancy (yet) just a git repo to check in code, checkout , branch etc. My coworker kept on getting this “resource cannot be null: source” error message.
When I am connecting to the same repo from my dev environment, I have no issues. In my case I was using the Visual Studio 2015 Enterprise with Update 3 and my friend was using Visual Studio 2017 Enterprise Update 2.
There is a nice topic going on the stackoverflow. Check that out if you are having issue.
There should be a better fix soon. But for now, we are using Visual Studio 2015 to get around that annoying issue.
