Fabric API - Items - Create Semantic Model REST API (SemanticModel) 202 uable to process error

[Anonymous]

Hi Everyone,

I’m currently exploring the Microsoft Fabric API, specifically the Items - Create Semantic Model REST API (SemanticModel) as detailed on Microsoft Learn. Items - Create Semantic Model - REST API (SemanticModel) | Microsoft Learn

I am facing error 202- 

<TridentPublicApiErrorResponse xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/Microsoft.PowerBI.ServiceContracts.Api.Public.Trident">

<errorCode>RequestFailed</errorCode>

<message>Unable to process the request</message>

<requestId>5646a7e7-2a72-450b-a232-27257442bd94</requestId>

</TridentPublicApiErrorResponse>

I am using structure for request boby content: 

post content:

 var content = new StringContent(
JsonConvert.SerializeObject(new
{
displayName = "SemanticModel 112",
description = "A semantic model description.",
definition = new
{
parts = new[]
{
new
{
path = "model.bim",
payload = modelBimBase641,
payloadType = "InlineBase64"
},
new
{
path = "definition.pbism",
payload = modelBimBase641,
payloadType = "InlineBase64"
}
}
}
}),

My questions are:

1. How can I create a semantic model Fabric API?

2.How to resolve the error.

3. Please help to provide sample request body content in Semantic model create.

4. Any another way for creating the semantic model uisng fabric API 

Any help would be greatly appreciated!

Hi @Anonymous,

Have you tried the same json payload in for example a tool like Postman? That might be an easier way to check if it is related to the body payload of the request or the actual code itself.

Btw, it is a long running operation, so it might return different status codes. For example a HTTP 202 response would be that the request is accepted, but that it is still busy with creating the model in the background:

And did you try the below example as well?
