GraphQL Endpoint not working on Preview tier of AEM as a cloud Service
Hi ,
I have published my Graphql and CF to preview tier , also i have published my Graphql endpoint and CF models ( these do not give explicit option to publish to preview tier , but simply gives publish). when i am trying to access my GraphqL endpoint , I am getting below errors in the preview tier logs. The Graphql endpoint is working fine in author tier and publish tier
com.adobe.aem.graphql.impl.servlet.PersistedQueryServlet Error processing persisted query: status code - 500, details - {"errors":[{"errorType":"ServletError","message":"Internal Servlet Failure","details":"No suitable endpoint found."}]}
I checked the documentation and it says that publish the Graphql endpoint will publish to all the environments which i feel means both preview and publish tier

Can you please help on this and what step am i missing to make it work on the preview tier of the environment
Thanks,
