Navigate to Identity -> ID Views -> Create new ID view -> Add user to override -> Click on the user -> View console's batch command.

{ error: "invalid 'params': Unknown option: idoverrideuser", error_code: 3008, error_name: "ConversionError", … }

Webui sends a batch request with cert-find and options idoverrideuser, the idoverrideuser is not defined and always results in a failure, as this is not being used in any way, it should be safe to delete.
