Error creating ACR Service connection with Service Principal Bearer token

[XtratusCloud]

Executing the following request to the Azure DevOps REST API for the creation of a Service Connection of type ACR, the endpoint fails with the error "A valid refresh token for identity 1fd109e5-3592-7532-7532-9201-1b545d36bdb2 was not found."

POST: https://dev.azure.com/{{organization}}/{{projectName}}/_apis/serviceendpoint/endpoints/?api-version=7.1-preview.4
Headers:

• Authentication: Bearer {{ServicePrincipalAccessToken}}
  Request Body:
  {
  "data": {
  "registryId": "/subscriptions/{{subscriptionId}}/resourceGroups/{{resourceGroup}}/providers/Microsoft.ContainerRegistry/registries/{{acrName}}",
  "registrytype": "ACR",

  },

  "description": "ACR Service Connection for {{acrName}}."
  }
  ]
  }

Making the request with an Access Token from an Azure AD user, the request works correctly.
In both cases, the credentials used have the following permissions (as at least).:

• Application Administrator role in Azure AD.
• Member of Endpoint Creator group in DevOps Project
• User Access Administrator role in Azure subscription.

Hi @XtratusCloud, Will you please let us know which lab from Azuredevopslabs page you are pointing to?. This will help us to provide you inputs on the concern

Hi @surajshenoy, the request and the issue reported is related to the DevOps REST API, and not related with Azuredevopslabs.
Probably I have opened the incident in the wrong place.
