Add UNKNOWN status code to retryable Quantum Engine errors #6565

Closed wcourtney closed 5 months ago

wcourtney commented 5 months ago

Users have reported intermittent errors where requests are halted due to a timeout. Within a provided stacktrace, I found:

<AioRpcError of RPC that terminated with:
    status = StatusCode.UNKNOWN
    details = "408:Request Timeout"
    debug_error_string = "<...>"
>

The stack trace also indicated that the _is_retryable_error check failed and so raised the exception.

This change adds the UNKNOWN error code to retry in these cases.
