Bonobo.Git.Server configuation

Can someone explain this error to me? I am fairly new to Jenkins and I am trying to configure it to get push notifications with my bonobo.gitserver. When I build the job I get the below error

java.lang.IllegalArgumentException: Invalid refspec refs/heads/**

Hello @tcs and welcome to this community :wave:

How did you configure your branch specifier? Prefer */* when possible.
You could also uncheck Lightweight Checkout if you have checked it.
I hope this helps.

When I leave it as / it gives the error message that it is unable to find the JenkinsFile although it is in the root of the repo.
