get_available_regions for the 'sagemaker-a2i-runtime' service returns no regions / service endpoints

[jvanbuel]

Describe the bug

When using get_available_regions api for the 'sagemaker-a2i-runtime' service, no regions / service endpoints are returned. I believe the underlying reason is that the service is not yet included in botocore/botocore/data/endpoints.json. Instead of submitting a PR to edit this file, I am submitting this issue, as suggested by the Contributing guide.

Steps to reproduce

import botocore.session

sess = botocore.session.Session()
sess.get_available_regions(service_name='sagemaker-a2i-runtime', partition_name='aws', allow_non_regional=True)

returns an empty list []

Expected behavior

I expected to receive a list of available regions and endpoints. The following boto3 snippet does allow me to list endpoints for the service:

import boto3
sess = boto3.session.Session()

a2i_runtime = sess.client(service_name='sagemaker-a2i-runtime')
a2i_runtime._endpoint.host

returns 'https://a2i-runtime.sagemaker.eu-west-1.amazonaws.com'

Hi @jvanbuel,

Thanks for raising this. The endpoints file is autogenerated, so any pull requests there would be overwritten later anyways. Thanks! The endpoints can be automatically inferred without being in the endpoints file, hence why you still get one when you instantiate a client. However knowing ahead of time which regions are supported is useful. I'm going to check in with the SageMaker team to clarify.

Generally you can also read about service endpoints in the documentation, but I don't see any for A2I either:

• https://docs.aws.amazon.com/general/latest/gr/sagemaker.html
• https://docs.aws.amazon.com/general/latest/gr/a2i.html
