It seems like you’re trying to add a new custom dimension in GA4 which might not be created at the GA4 interface first. You have to create it there and ensure it’s correctly set as an event-scoped dimension. Getting the data through Java could be more about API querying. If you’ve got the dimension set right, then it might be more about properly fetching the data with the right API call.
