Unable to de-serialize error when using the git path material plugin

[James Wright]

My company has recently moved from svn to git for source control so I have a legacy application that consists of multiple projects which all reside in the same git repository (not ideal I know). Now I have been attempting to use the git path material plugin to setup CI for specific components, however I am getting the bellow error message and due to receiving this error go is repeatedly trying to download the code into the flyweight directory. Anyone else encountering this? Running 20.2.0 on Windows.

(changed the uri path slightly and * out the user id)

Let me take a step back on this and ask if anyone has an example of how to properly configure a git path material?

I'm not sure that plugin has been maintained. Maybe it's worth opening an issue there to see if anyone knows?

Cheers,
