I created a very simple custom connector, with a single action. There is an existing standard connector for this web service, but it does not support a specific REST API call/action that I need, so I created a custom connector with that missing action.
I can connect and maintain the connection for the standard connector without any issues. But for the custom connector, I find that any connection I create expires ("Invalid Connection" error) in less than a day. I can't understand why the connection expires so quickly.
