Endpoint with ID '{endpoint_id}' was not found in pass-throu

Error message

Endpoint with ID '{endpoint_id}' was not found in pass-through endpoint list.

What it means

While removing a pass-through endpoint, the config's pass_through_endpoints list was loaded successfully but contains no entry whose ID matches the supplied endpoint_id — the endpoint was already removed or the ID is invalid.

Solutions

1. Fetch the current pass-through endpoint list and use an ID present in it.
2. Recreate the endpoint if it was removed from the configuration.
