Snowflake connector: "We cannot convert the value null to type Text"
- 3 months ago
Also i recieved reply from Snowflake
After investigation across multiple cases reporting the same issue, engineering has confirmed that this is a regression in the Power BI Desktop June 2026 release (2.155.756.0) — not a Snowflake-side change. The SNOWFLAKE application database has always returned empty owner/owner_role_type fields for APPLICATION-type databases, but the June release of Power BI Desktop introduced a change in how the connector handles null values during database enumeration, causing the "We cannot convert the value null to type Text" error.
Resolution:
Rolling back to the May or April 2026 version of Power BI Desktop resolves the issue immediately. You can download previous versions from Microsoft's Power BI Desktop release archive.
But SNOWFLAKE app DB - system db, i can't do anything with it
Snowflake support just thinking what they can do
That’s correct. The SNOWFLAKE application DB is system‑managed, so nothing can be changed on your side. Snowflake support can’t change those null fields either. The issue is on the Power BI connector side.
