Need to fix issue in Create Semantic Layer by providing sql query

Hi, UmeshGoti 

Based on your description, I made a working case.
First, I created a basic semantic model in Power BI desktop:

Save it as a PBIP file:

Use the following template to make a payload:

SemanticModel definition - Microsoft Fabric REST APIs | Microsoft Learn

The format should look like this:

{
  "displayName": "SemanticModel 1",
  "description": "A semantic model description.",
  "definition": {
    "parts": [....]
  }
}

Next, let's process the Parts section one by one:

According to the section in the part, the content of each file in the folder is encrypted:

definition/database.tmdl
definition/model.tmdl
definition/tables/Table1.tmdl
definition/model.tmdl
definition/tables/Table.tmdl
definition.pbism
diagramLayout.json
.platform

Here I'm using Python to send requests. My script is as follows:

I'm using service principal authentication:

import requests
from azure.identity import ClientSecretCredential

class MyAPI:
    def __init__(self,client_id,client_secret,tenant_id):
        self.scope = 'https://analysis.windows.net/powerbi/api/.default'
        self.grant_type = 'client_credentials'
        self.client_id = client_id
        self.client_secret = client_secret
        self.tenant_id = tenant_id
    def auth12 (self):
        cred = ClientSecretCredential(
            authority = "https://login.microsoftonline.com/",
            tenant_id=self.tenant_id,
            client_id=self.client_id,
            client_secret=self.client_secret)
        acc_token = cred.get_token(self.scope)
        return acc_token.token
    
api = MyAPI(
    client_id = 'xxxx',
    client_secret = 'xxxx',
    tenant_id = 'xxx'
)

workspaceId = 'xxxx'

urlPost = f"https://api.fabric.microsoft.com/v1/workspaces/{workspaceId}/semanticModels"
bodyPost = {
  "displayName": "SemanticModel 1",
  "description": "A semantic model description.",
  "definition": {
    "parts": [
        {
            "path": "definition/database.tmdl",
            "payload": "xxxx",
            "payloadType": "InlineBase64"
        },
        {
            "path": "definition/model.tmdl",
            "payload": "xxxx",
            "payloadType": "InlineBase64"
        },
        {
            "path": "definition/tables/Table.tmdl",
            "payload": "xxxxx",
            "payloadType": "InlineBase64"
        },
        {
            "path": "definition.pbism",
            "payload": "xxxx",
            "payloadType": "InlineBase64"
        },
        {
            "path": "diagramLayout.json",
            "payload": "xxxxx",
            "payloadType": "InlineBase64"
        },
        {
            "path": ".platform",
            "payload": "xxxxx",
            "payloadType": "InlineBase64"
        }
    ]
  }
}
token = api.auth12()
headers = {
    'Authorization': f'Bearer {token}',
    'Content-Type': 'application/json'
}

res = requests.post(url=urlPost,headers=headers,json=bodyPost)

print(res.status_code)

It gets the right repercussions code and sets up the right semantic model on Power BI Service:
