Hi @jamaalscarlett,

I just made a quick pass on the failing pipelines are they are totally unrelated to your PR. Apparently, we ran out of metrics uploading to CodeCov and the workflow is been throttled (rate limited) hence, actions is failing as it is unable to upload metrics.

Thanks for the PR.

I'd just restart the workflow, rebase and merge.
