ranjith13119-gmail.com was able to solve the issue by doing the following things:

1. The error "No database connection" was happening because the custom handler was not invoked for the Graph entities and due to the missing "@cds.persistence.skip" annotation on the entities the CAP framework assumed it needs to query the database to fetch results.
2. The destination was changed to use "No authentication". Instead, the JWT for accessing the Graph API is forwarded to the destination in the "Authorization"-header as a bearer token.
