Scenario:
Only creator of the customer connector and its connection can use it inside of an Power App.

All other users get it to fail, if you trace it you can see error message 500 "Setting 'gateway' cannot be null' (can be seen with the trace inside of Power Apps).

All users can use the test page inside of the custom connector to make the call to the custom connector.

So in short - for creator the connection keeps the gateway but all other are not allowed somehow and that makes the connection to think there are no gateway set up for it.

We have tested adding user as admin on gateway, co-owner on app and can edit on connector.

It is a pay as you go environment and other connectors like SQL Database works like a charm for everyone. The custom connector is a post call to an azure function.
