Why does this setting keep returning 502 Bad Gateway when i try to POST to my dead letter queue endpoint? The initial webhook fails with a 5xx, so i’m trying to catch it in a lambda, but the retry payload is malformed.
{
"event": "message.status.updated",
"data": null
}
The webhook docs don’t mention how to handle the body on retries. just hanging here.
The official documentation states the body must be valid json.
data: null breaks the parser.
send an empty object instead.
This is actually a known issue… The point above is correct, the parser chokes on null data. Check the webhook payload spec for the exact schema requirements.
this looks like exactly what i’m hitting with my token refresh logic. the parser fails hard on nulls. tried swapping it for an empty object {} and the 502 vanished. weird that the docs don’t scream this out. saved me an hour of debugging.
