Hi @NichithaM ,
- To check the pipeline configuration, navigate to App Engine Studio > Configuration > Pipeline
- Confirm if both Dev environment and Prod environment are configured.
- If any of the two environments is not set, create a new Environment from App Engine Studio > Configuration > Environment. In case you do not have a valid second environment to set up, you can configure any invalid instance URL and there is no validation done to check the URL at this stage. You will only face issues when trying to move application across instances using the pipeline.
- Select the new Environment record in the pipeline configuration where either dev or prod environment was not configured.
Launch App Engine Studio again and confirm that the screen with the message no longer appears and the page loads as expected.
