RocketMQ error

Error message

RocketMQ error %d: %s

What it means

Returned by invokeRemotingAllowCodes in the rocketmq driver when a synchronous remoting request succeeded at the transport level but the response code is not in the allowed-codes set for that operation. The message shows the RocketMQ response code (e.g. topic not exist, no permission, system error) and the server's remark string.

Solutions

  1. Map the numeric code to its RocketMQ meaning (e.g. 17=QUEUE_NOT_EXIST-like errors, 16 message illegal, 1 system error) and follow the remark hint
  2. For topic/group errors verify the topic exists and the group id is correct
  3. For permission errors check ACL access_key/secret_key and broker ACL config
  4. Retry transient system-error codes; fix configuration for permanent ones
Defensive patterns

Strategy: try-catch
