Could someone advise me as to what is blocking? The 3 tests that are failing are doing so in "build" phase. It is not clear how that is connected to my change. What are the next steps

You can just enter details section of each check and see errors by yourself. 1 and 3 are obviously introduced by your code, so you should fix them. 4 is definitely unrelated to your code as I saw it in other PRs, 2 is likely unrelated - I triggered a rerun for it. I also approved all checks for your PR, so you may expect some more fails.
