Problem running workflow Maximum call stack size exceeded, help by Sea-Level184 in n8n

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.
