Pod CrashLoopBackOff after gitlab eventsource created

[JulianZhang]

Dear

I had create gitlab eventsource as example in master https://github.com/argoproj/argo-events/blob/master/examples/event-sources/gitlab.yaml.

The pod for the eventsource will be created, But will fail to CrashLoopBackOff status.

The error in log is as blow, it saws "Invalid url given", But the "http://gitlab.xxxx.com/api/v4/projects/334/hooks" url can be used to list hooks for that project.

I don't know how to fix or workaround it. I had try to create hook manually, but I don't know which url should used in hook.

We had similar issue yesterday.
In our case the URL was right, but we had to increase the GitLab account rights in the repo (from Developer to Maintainer).
Maybe this might else somehow.

I had fix the problem, by add "http://" to gitlabBaseURL.
