Hey @shivamSingh,

Thanks for sharing the details. Just to double-check, could you confirm that the table name is spelled exactly right (including case), and that you’re connected to the correct database? It might also help to make sure the table exists in the public schema. Let me know what you find and happy to help however I can.

The table name is right and i am connected to the database. For eg i tried different question for which it provided correct answer. The error is somewhere in the sql query that it executes like for one sql query " Select ScrumTeam from CCPM_Apollo" in this case it was pointing towards ScrumTeam as the error it also suggested “Did you mean CCPM_Apollo.ScrumTeam”.
