Using graphql-inspector validate for gitlab repository

[Burnett2k]

Hi there,
For our graphql inspector use case, we want to validate Pull Requests against production where introspection is turned off. That means we can't point to the graphql endpoint.
Previously, we pointed to github using the format mentioned in the docs of git:ref:path/to/file i.e. github:<orgname>/repo/path-to-file.

However, we recently migrated to gitlab and need to point there instead. I've noticed the Gitlab urls are a bit different. There are more levels involved such as git:owner/subproject/project/repo/path-to-file/etc. I've tried pointing to gitlab using this similar format and it doesn't seem to work. I get a fetch error. I will also mention I did pass in a Gitlab token which has access to read the repository, so I don't think it is a security issue.

Do you have any guidance or docs on if pointing to other git providers or alternative ways of making this work?

After reviewing the inspector code a bit more, it seems like gitlab will not work out of the box in a similar way to the github string. I suppose the alternatives in my situation are:

1. Try and make the schema available and use the git loader (have both repositories cloned in the same pipeline) OR
2. Implement a URL loader function which will correctly retrieve the schema file and pass that into the validate function. It's still unclear to me what the URL loader actually needs to retrieve.
