I have a Logic app that establishes a connection to DevOps via the standard connector.
Here I perform various activities (GetQuery, Update Item…)
Since 10 June it no longer runs reliably and sometimes in a loop it gives the following error for an item:

Used connector -> https://learn.microsoft.com/en-us/connectors/visualstudioteamservices/

Code:

{
  "type": "ApiConnection",
  "inputs": {
    "host": {
      "connection": {
        "referenceName": "visualstudioteamservices"
      }
    },
    "method": "get",
    "path": "/_apis/wit/workitems/@{encodeURIComponent(items('For_each_DevOps_Item')?['System.Id'])}",
    "queries": {
      "account": "@variables('account')",
      "project": "@variables('DevOpsProject')",
      "typeName": "@{items('For_each_DevOps_Item')['System.WorkItemType']}"
    }
  }
}

It also happen when i not use a variable as account, that was the initial setup for over one year.

Code:

{
  "status": 400,
  "message": "The account name you entered is invalid. Enter 'fabrikam' if your Azure DevOps URL is 'fabrikam.visualstudio.com'.rnclientRequestId: XXXXXXXXXX",
  "error": {
    "message": "The account name you entered is invalid. Enter 'fabrikam' if your Azure DevOps URL is 'fabrikam.visualstudio.com'."
  },
  "source": "vsts-we.azconn-we-002.p.azurewebsites.net"
}

Does anyone know the problem?

I have already tested everything:

• Connection API re-verified
• Checked authorisations
• Nobody has changed anything …
