Issue trying to get Semantic Model via api

[ddelapasse]

I'm making a post to {baseUrl}/workspaces/{workspaceId}/semanticModels/{semanticModelId}/getDefinition and I get a 202 with a Location url in the response header.   Then, I am doing a get to that Location url which looks like: https://wabi-us-east2-b-primary-redirect.analysis.windows.net/v1/operations/{guid}.  That returns 200.

I get only this json though: {"status":"Succeeded","createdTimeUtc":"2024-11-07T15:41:21.2885946","lastUpdatedTimeUtc":"2024-11-07T15:41:21.8198463","percentComplete":100,"error":null}

How do I get the actual semantic model json?  Is there any documentation of the handling of the 202?  Maybe something else is required?

What you are describing in the behavior of long running operations in Microsoft Fabric APIs.

For APIs which return a result, like the "getDefinition", once the "Get Operation State" returns 200 with status:Succeeded, it will contain another URL for fetching the result. It should look like this in your case:
 https://wabi-us-east2-b-primary-redirect.analysis.windows.net/v1/operations/{guid}/result

Seems to be an inofficial endpoint?  The regular API still uses the "dataset" term.
