I saw this issue about 2 months ago and it hasn't been fixed yet.
When using a Looker Studio dashboard with the Report Publishing feature activated, I encountered an issue while implementing it as a connector template in the appsscript.json file. Specifically, the data source was disrupted during the report creation process.
This problem was resolved by disabling the Report Publishing option in the template. Could you please address this bug?
I tested another scenario: I used a template with activated Report Publishing, then made a copy and added a data source with my connector ID. In this case, reports were created properly, and no issues occurred.
