Issue Creating New Semantic Model – Datamart Folder Error

[ViganGashi]

Previously, I was able to create semantic models from the same lakehouse. There are already existing semantic models built on top of this lakehouse. However, now when I try to create a new one, I receive the following error message:

{"code":"InvalidOperationException","message":"Condition 'A datamart folder should exist' should not be false in method 'ModelingService.exe!Microsoft.PowerBI.ModelingService.ModelExtensions+<GetDatamartConnectionInfo>d__2.MoveNext' (MoveNext at offset 692 in file:line:column D:\\a\\_work\\1\\s\\Sql\\CloudBI\\AS\\src\\PowerBI\\ModelingService\\Utils\\ModelExtensions.cs:55:13\r\n)"}

Based on the information I have, there is no datamart created, nor have any changes been made that could have caused this issue.

Has anyone experienced something similar and found a solution? I want to avoid creating a new lakehouse or re-creating items.

Apologize for the late reply, no unfortunately the suggestions didnt work, we ended up creating a new lakehouse. I will accept as a solution the comment that suggests opening a ticket.

Hi @ViganGashi ,
Thanks for reaching out to the Microsoft fabric community forum.

Try creating a new semantic model using the SQL Analytics endpoint to determine if the issue persists.
Additionally, verify that the Lakehouse is accessible, contains all the expected data, and has no underlying issues.

Thanks and Regards
