@yschimke Apologies for replying so late, but when I tried to check out the branch in the reproducer, I am getting the following error: git checkout 7842d7da9f89d99b85f6a539a146b678c7558417 fatal: reference is not a tree: 7842d7da9f89d99b85f6a539a146b678c7558417

Hi @yschimke any update on this?

[yschimke]

@mcraj017 my bad, I had pushed my commit to my fork, not the square org repo. I've updated the PR (SHA bff87d1fc6bf1527a4052b0b5251fab53238f714) and pushed to square org. Should work now.

This workaround fixes it
