Camunda 8.8 Connector Management: An error occured

[KevinHang]

For Camunda 8.8, deployed using the docker-compose-full.yaml, in the Console dashboard under Connector Management, it always shows "An error occurred".

In the Console container logs, I see the following:

I was able to make the Connectors Management work by updating the console component to use the correct internal Connectors URL.

In the .console folder, you have the application.yaml, where you need to update the Connector's URL from "localhost:8086" to "connectors:8080". This fix works for both the 8.8 and 8.9 versions.

Please let me know if this fix is valid, as I am now able to see the connectors:
