Hi Anonymous ,
Thank you for reaching out to Microsoft Community.
From the documented endpoints: Items - REST API (Reflex) | Microsoft Learn
There is no supported entity type listed for Power BI SemanticModel, Report, or Dashboard as a Reflex metric source. The ItemType enumeration includes SemanticModel, Report and Dashboard, but only as item types, not as supported Reflex source entities.
This confirms that the Reflex REST API does NOT support Power BI Semantic Model based metric alerts.
The error you are receiving: Entity type powerBiMetricSource is not supported.is therefore expected behavior per the current API surface.
Hope this helps.
Thank you.
