Azure Devops unable to populate picklist - azure

Question

I followed the tutorial found at
https://learn.microsoft.com/en-us/azure/devops/extend/develop/service-endpoints?view=azure-devops
The api call is right because if I don't authenticate it shows the correct path in the error message. Entering the url that it shows in the message in a browser gives the correct json.
The picklist object will act like it is trying to load but will end up showing no results found.
Can you use a personal company api to load a picklist using server endpoint?
How do you debug this. All I see in the network tab on debugging tools is the 200 from azure making the post.
This is the JSON
