generate_measure_descriptions user doesnt belong to cluster issue

[jozsefbraun]

Dear Team!

I would like to invoke generate_measure_descriptions() function inside a Fabric Notebook, but I get the following error:
FabricHTTPException: 401 Unauthorized for url: https://api.fabric.microsoft.com//explore/v202304/nl2nl/completions
Headers: {'Content-Length': '0', 'X-PowerBI-Error-Info': 'UserDoesNotBelongToCurrentCluster', 'X-PowerBI-Error-Details': "Current user belongs to cluster '', but this request was sent to cluster: 'WABI-NORTH-EUROPE-redirect.analysis.windows.net'.", 'request-redirected': 'true', 'home-cluster-uri': 'https://wabi-north-europe-m-primary-redirect.analysis.windows.net/', 'Strict-Transport-Security': 'max-age=31536000; includeSubDomains', 'X-Frame-Options': 'deny', 'X-Content-Type-Options': 'nosniff', 'Access-Control-Expose-Headers': 'RequestId,X-PowerBI-Error-Info,X-PowerBI-Error-Details', 'RequestId': 'xxx', 'Date': 'Tue, 14 Jan 2025 15:34:48 GMT'}

I get the same results with a specific measure + readonly = True and no measure defined + False settings.

My workspace is attached to a P4 capacity, my user is also part of the user group who can use Copilot feature and I am a Fabric administrator as well.
(Also, randomly connect_semantic_model() doesnt find my model saying that it doesnt exist, but it's clearly there - I used another capacity in the beginning then i attached that P4, probably that object movement messed it up?! (even after hours))
Could you please help me finding the issue?

Thanks
Jozsef

You must run this function on an F64 sku or higher as documented here.
