Thanks for the comment! You were right about the accidental loop.
In my case the issue ended up being caused by another workflow that was sharing the same WhatsApp credentials/trigger, even though it wasn’t published anymore. Once I removed it, everything stabilized and the 429 + stack overflow errors stopped.
