I have the same issue, looking at the above its fixed so I guess we have to wait for 2022.4.1 to be able to use this fix?

Sorry guys, I never did try (or test) the broadcast platform. Clearly it broke in the refactor ☹️
It's good to see a test for it now so it won't happen again 👌
I guess a workaround would be to use one of the other platforms until the fix is out? webhook might not be for everyone but polling should work, right?

And thanks for the quick fix @balloob!
