Plugin Validation Fails: "Error: fatal: couldn't find remote ref refs/pull/4678/merge"

I am working through my first plugin submission. My initial pull request was validated successfully, but changes were needed upon manual review. Now that I have made those changes and updated my pull request, then validator bot is throwing an error I cannot figure out.

In “Fetching the repository”:
