@rohan_dhunde - this error occurs when there isn’t a sql schema created for your underlying collection/table. Please follow these steps to generate the SQL Schema for this collection or for the whole federated database instance:
This functionality to regenerate the SQL Schema will soon be available within the Atlas UI (saving you the trip to mongosh). But for now, if you log into mongosh and run the sqlGenerateSchema command for this collection that should do the trick. It typically gets created automatically, but perhaps this did not happen or the shape of the collection changed dramatically.
