I am experiencing a persistent error when using Genie Space integration within a Databricks Dashboard (v3/Lakeview). While Genie works perfectly as a standalone Space, it consistently fails when invoked via the Dashboard sidebar.

Environment:

• Edition: Databricks Free Edition

• Warehouse: Serverless Starter Warehouse (Status: Running)

• Data: Unity Catalog tables (main.schema.table format)

The Issue:

1. In the Genie Space UI, natural language queries (e.g., "show 5 rows") work fine and generate SQL/results successfully.

2. In the Dashboard sidebar (Ask Genie), the exact same queries fail immediately.

3. The error message shown is: Details: Agentic SQL generation failed: GenericChatCompletionServiceException: Chat completion failed

What I have tried so far:

• Permissions: Set Genie Space sharing to "All workspace users" with "Can Manage" permissions.

• Linking: Tried linking the Genie Space using both the full URL and the specific 32-character Space ID.

• Isolation: Tested in Incognito/Secret mode to rule out browser cache issues.

• Data Re-indexing: Removed and re-added all tables in the Genie Space and ensured they are fully indexed.

• Dashboard Settings: Published the dashboard with "Share data permission (default)" and tried various Locale settings (Japanese and English).

• Warehouse Check: Verified the Serverless Warehouse is fully "Running" and "Connected" before querying.

Despite these efforts, the sidebar remains non-functional while the standalone Genie Space works.

Has anyone encountered this specific GenericChatCompletionServiceException only within the Dashboard context? Is this a known limitation of the Free Edition, or is there a specific session/authentication configuration I might be missing?

Any insights would be greatly appreciated.
