The signal is not found.

500

An internal error occurred while processing the request.

503

The service is currently unavailable. This may happen only on some requests where the system creates backpressure to prevent the server's compute resources from being exhausted, avoiding more severe failures. In this case, the title of the error object contains RESOURCE_EXHAUSTED. Clients are recommended to eventually retry those requests after a backoff period. You can learn more about the backpressure mechanism here: https://docs.camunda.io/docs/components/zeebe/technical-concepts/internal-processing/#handling-backpressure .
