# 80503: No Records Updated

Log Level: WARNING

## Description

Twilio returns this warning when an update request in Proxy does not modify any records because the target record cannot be found. This usually means the resource you tried to update no longer exists, was already removed, or does not match the parent `ServiceSid` or `SessionSid` in the request path.

### Possible causes

* The `Sid` in the request does not identify an existing Proxy resource.
* The resource was deleted before the update request ran.
* The request used the wrong parent `ServiceSid` or `SessionSid`, so Twilio could not find the record under that parent resource.
* You tried to update a Participant after it had been removed from the Session.
* The Session was deleted. Deleting a Session permanently removes the Session and its related Participants and Interactions.

### Possible solutions

* Fetch the resource before updating it to confirm that it still exists and that you are using the correct SID.
* List the current resources in the parent Service or Session and retry the update with the active resource SID.
* Verify that the request path uses the correct parent `ServiceSid`, `SessionSid`, and resource `Sid`.
* If the resource was deleted, create a new resource instead of retrying the update against the deleted one.
* If you need to replace a Participant in a Session, remove the existing Participant and add a new one to the Session.
