Azure App Service Problem in DevOps Pipeline

Question

Hi does anyone have any idea on why im getting this error:

Got service connection details for Azure App Service:'nsclassroomstudent-dgyn27h2dfoyo'
##[debug][POST]https://login.windows.net/***/oauth2/token/
##[debug][GET]https://management.azure.com/subscriptions/237bc9da-22ad-49ea-8411-6cf6a190c18f/resourceGroups/ClassroomInTheCloud/providers/Microsoft.Web/sites/nsclassroomstudent-dgyn27h2dfoyo/?api-version=2016-08-01
##[debug]Correlation ID from ARM api call response : c3eefa7c-9088-44f1-8dc8-dccd7a9f8c4c
##[debug]Processed: ##vso[task.logissue type=error;code=ResourceNotFound;]
##[debug]Deployment Failed with Error: Error: Failed to fetch App Service 'nsclassroomstudent-dgyn27h2dfoyo' details. Error: The Resource 'Microsoft.Web/sites/nsclassroomstudent-dgyn27h2dfoyo' under resource group 'ClassroomInTheCloud' was not found. For more details please go to https://aka.ms/ARMResourceNotFoundFix (CODE: 404)
##[debug]task result: Failed

My code is attached, I have been through the microsoft Site: https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/deploy/azure-app-service-settings?view=azure-devops

I have added the Connected Service Name to my YAML but I still get the error and im not sure what else it wants.

Thanks

I ended up fixing this, when changing app settings on an app you have to put in the app name in the displayname area in the code like so:

- task: AzureAppServiceSettings@1
  displayName: 'Azure Web App Deploy: $(webappname)'
    inputs:
      azureSubscription: $(azureSubscription)
      ConnectedServiceName: $(appconnectionname)
      appName: '$(webappname)'
      resourceGroupName: $(RG)
      # To deploy the settings on a slot, provide slot name as below. By default, the settings would be applied to the actual Web App (Production slot)
      # slotName: staging
      appSettings: |
        {
          "name": "DIAGNOSTICS_AZUREBLOBCONTAINERSASURL",
          "value": "VALUEINHERE",
          "slotSetting": false
        },
        {
          "name": "DIAGNOSTICS_AZUREBLOBRETENTIONINDAYS",
          "value": "365",
          "slotSetting": false
        },
        {
          "name": "OEM",
          "value": "netsupport",
          "slotSetting": false
        },
        {
          "name": "SCM_REPOSITORY_PATH",
          "value": "d:\\home\\respository",
          "slotSetting": false
        },
        {
          "name": "VIDEO_CLIENT_URL",
          "value": "https://signal-uks.classroom.cloud",
          "slotSetting": false
        },
        {
          "name": "WEBSITE_NODE_DEFAULT_VERSION",
          "value": "10.15.2",
          "slotSetting": false
        }

I got to this conclusion after playing around with the classic pipeline editor and watching what it would do to the YAML code.
