Invalid url for get reference endpoint? #1037

While this code works fine for most use cases:

It looks like that GET /refs/{ref} is an undocumented endpoint and it returns an array of references when an exact reference is not found, but other similar references are found in the repo.

Current GitHub docs tells to use GET /ref/{ref} URL: https://docs.github.com/en/rest/reference/git#get-a-reference

My story: I have the following references in the repo:

• accepted-1-1
• accepted-1-1-1

When I try to get accepted-1 reference using references()->show(..) I get the following response, but I expect zero results:

If I change GET /refs/{ref} to GET /ref/{ref} in References.php it starts throwing a 404 not found exception as expected.
