Getting 404 on Powershell Query of Cosmos DB

Question

I'm using this script from the download in this link. https://gallery.technet.microsoft.com/scriptcenter/How-to-query-Azure-Cosmos-0a9aa517 However for some reason I am getting a 404 response.

I copy-pasted the url of the db directly. Putting in a fake URL gives me a "could not be resolved" error so I know the location exists.

Based on the Azure CosmosDB API documentation here: https://docs.microsoft.com/en-us/rest/api/documentdb/databases the $databaseID is user-set and just has to be unique, so I've set it to be the same as the db name and assigned that to the url.

Changing it to be different still gives me the same 404 response message (below).
