Error:

This is blocking sourcegraph/sourcegraph-typescript#8

I don't anticipate having time to investigate this in the next 24 hours.

The trace indicates that reposource.CloneURLToRepoName(*args.CloneURL) is returning an empty string and no error.

The function does that when there are no registered repo sources in the configuration which can interpret the URL: https://sourcegraph.sgdev.org/github.com/sourcegraph/sourcegraph/-/blob/pkg/conf/reposource/common.go#L71

@beyang thoughts on the above since you wrote the package? what is a good solution here?

@felixfbecker warning: I will not have time to look into this further until at least Mon.

Thanks, I added a check for the empty string in https://github.com/sourcegraph/sourcegraph/commit/8821f9653a7c4959a3a93dff59853caa0b62ddaa, but it will not fix the issue of course.

So does prod not have configured "repo sources" for GitHub and Gitlab? @beyang
