Document intelligence Layout : Connected container getting Invalid Billing Endpoint URI

Question

Affected Service : Azure document intelligent : connected container ( layout 3.1 mode)

Followed tutorial : https://learn.microsoft.com/en-us/azure/ai-services/document-intelligence/containers/configuration?view=doc-intel-3.1.0&preserve-view=true

environment : Windows 11

i have enable Commitment plans for above, but now i cant connect to the service from the container , i have given the billing (URL) and ApiKey correctly.

i am getting Invalid Billing Endpoint URI.

NOTE :

1. For the same Endpoint and KEY 1 of the same Document intelligence resource i can use the service with npm package / SDK.
2. Further with another Document Intelligence resource in the same subscription and without a Commitment plans container is working fine without the error ( can connect) .

docker-compose :
