Troubleshoot connector list unavailable in Apache Kafka® Connect
When you try to view connectors in Aiven for Apache Kafka® Connect, you might see the message connector list not currently available.
This means the Kafka Connect service failed to return the list of installed connectors.
Aiven Terraform Provider also displays the connector list not currently available message, for example when running terraform plan, because it uses the same backend API as the Aiven Console.
Common causes and solutions
Kafka Connect service is starting
If you recently created the service, wait 2 to 5 minutes for all nodes to become fully operational. The connector list loads automatically after initialization.
Kafka Connect was recently enabled
After you enable Kafka Connect on an existing Kafka service, the service takes 30 to 60 seconds to initialize. Refresh the page after that.
Connector creation or update in progress
During connector creation or updates, the list might be unavailable for 10 to 30 seconds. It refreshes automatically after the operation completes.
Kafka Connect service is low on memory
If the service is running out of memory, the connector list might continue to be unavailable. Upgrade to a larger service plan to resolve the issue.
One of the Kafka Connect nodes is unavailable
The connector list is retrieved from a randomly selected node. If a node is unavailable, the request might fail intermittently. The node usually recovers automatically. If the issue persists, contact Aiven support.
