"Error fetching data for this visual" in Snowflake

Hi Danyboyyy ,

Thank you for reaching out to Microsoft Fabric Community.

These steps might resolve the “Invalid credentials” and DirectQuery visual errors for non-workspace users in apps.

1. Grant Build permission on the dataset to the app audience users, navigate to Workspace which contains Dataset, click on Manage Permissions, Add users, Grant Build Access.

2. Enable SSO correctly:

   • Go to Workspace , click on dataset settings expand data source credentials.

   • Ensure “Use SSO via Azure AD” is enabled and “Use user's credentials” is checked.

3. Verify Snowflake access, Ensure app users have the right Snowflake roles and are not blocked by network policies.
