Question Problem Deleting User with Authentication API

I have a Cloud Code script that creates users to hold information about player groups (it's poor architecture, but I have been outvoted). I am working on a script to delete those users as well. However, I get an authentication error when attempting the deletion. Could someone suggest what I might be doing wrong here?

Here is my Cloud Code script. It is based upon the Delete User section of the Clint Authentication doc. I have a Service Account set up for the application with all 3 Authentication roles added.

Code (JavaScript):

1. const axios = require("axios-0.21");
2.  
3. module.exports = async ({ params, context, logger }) => {
4.   const { projectId, playerId, environmentId, accessToken } = context;
5.   const { groupId } = params;
6.  
7.   //Delete the user that owns the group (groupId)
8.   const deleteUserUrl = `https://player-auth.services.api.unity.com/v1/users/${groupId}`;
9.   const deleteUserConfig = {
10.     headers: {
11.       'Authorization': `Bearer ${accessToken}`,
12.       'ProjectId': projectId
13.     }
14.   };
15.   const response = await axios.delete(deleteUserUrl, deleteUserConfig);
16. };

And the response:

Code (JavaScript):

1. Invocation Error
