Power Automate not working for secured feature service

[AustinWolf1]

Hi Everyone,

I recently created a flow through Power Automate based on the guide below that sends out an email whenever a new polygon is created in an ArcGIS Online feature layer: 

https://www.esri.com/arcgis-blog/products/field-maps/field-mobility/use-webhooks-to-automate-workflo...

Everything worked well until I decided to change the sharing status of the layer from Public to the Organization level. The flow now stops working at the "Check Status" step, within the "Check Status Until Ready" loop. My configurations are the exact same as this guide. The error log for that tool gave me the following response:

{
  "error": {
    "code": 499,
    "message": "Token Required",
    "messageCode": "GWM_0003",
    "details": [
      "Token Required"
    ]
  }
}

Thank you! If you need more information, I'll gladly answer any comments.
