Channel stuck in CREATING state - Amazon Managed Streaming for Apache Kafka

Channel stuck in CREATING state

  • Symptom: The Channel remains in CREATING for an extended period and does not transition to ACTIVE or FAILED.

  • Causes: Provisioning is still in progress, or a transient service-side delay. Configuration errors — such as missing service-role permissions, a destination or DLQ bucket that doesn't exist, or (for plain JSON) a schema that can't be resolved from GSR — cause the Channel to transition to FAILED rather than remain in CREATING. For JSON_SCHEMA_GSR, an unresolvable schema is detected during delivery, not at creation.

  • Resolution: Allow provisioning to finish. Run DescribeChannel to check the state — if it is FAILED, read the failure detail (and Amazon CloudWatch Logs, if enabled) to identify the configuration problem, then delete and recreate the Channel. If the Channel stays in CREATING well beyond the expected time, contact AWS Support.
