@AngiSen, may be related to a recent (breaking) update of Azure Cosmos DB resource provider (Microsoft.DocumentDb/databaseAccounts) as I just noticed today (28th of Nov 2018) that a previously running deployment (as of 23th of Nov 2018) of Cosmos DB Table API is now failing with this same error:
9:16:23 AM - Resource Microsoft.DocumentDb/databaseAccounts 'xxx-xxx-xxx' failed with message '{
"code": "BadRequest",
"message": "CORS rules are not supported for this API\r\nActivityId: xxx, Microsoft.Azure.Documents.Common/2.1.0.0"
}'
In my case I'm using 2015-04-08 version with Table API but I don't configure explicitly the CORS part and anyway there's no such configuration option in the resource provider.
Digging into the existing Cosmos DB instance with https://resources.azure.com shows there's indeed a CORS member that is part of the definition:

Hope it'll get fixed quickly if it's indeed a breaking change...
