I noticed this coming up a couple days ago, and assumed it was some sort of transient issue or something stupid I did and it wasn't stopping things from completing, so I've been letting it go. But it isn't resolving and as far as I can tell, it isn't on me, so what is happening with webhook responses?
Even when I just follow the suggestion for a return body:
And use the non-sense response, I get linting and "invalid JSON" errors (when I run the block, it works just fine):
Happens for a brand new workflow without me doing anything but adding a response block too:
I can work around this by adding a JS block and passing that as the return body...
...but I'd prefer to not have to go back through all my workflows and add a JS block before each response.
