Sometimes you will see the message "connector list not currently available" intermittently when trying to view the list of connectors in your Aiven for Apache Kafka Connect cluster in Aiven web console. You may also see this error message when using Terraform (e.g
terraform plan) because it calls the same API as the web console.
There can be a number of reasons why you are seeing this message. Here are the most common reasons:
The dedicated KConnect cluster was just created. The list will load after the cluster is fully online with all the nodes in running state
The KConnect API on a Kafka cluster was just enabled. It should take a few seconds for the KConnect services to be operational
The cluster is in the middle of setting up/reconfiguring a connector. This message should clear after a few seconds
The cluster is running out of memory. You will likely keep seeing this message unless you upgrade to a larger plan
One or more nodes on the cluster crashed. The API that fetches the connector list calls the KConnect cluster by it's hostname and that maps to either one of the 3 workers randomly. If you see this message appear intermittently, this is likely the reason. The crashed node should recover automatically, but if it doesn't, do contact our support to further help
If you are in doubt whether or not any of the following reasons above is the issue that you are experiencing, you can contact our support channel and we will be able to help you further.
