# X_WEBHOOK_ENDPOINT_UNKNOWN

## Means

no endpoint carries this id

## Typical cause

the `endpoint` seam answered nothing for an id a queued delivery names — usually an endpoint the app deleted between the enqueue and the attempt. Terminal: a queued delivery cannot invent a destination

## Fix

return the endpoint row for the id `cause` names from `webhook("<name>").endpoint`, or stop enqueueing deliveries for endpoints your app has deleted
