Why I can't create a serverless sagemaker endpoint anymore ?


I was able to create a sagemaker endpoint a few weeks ago using as endpoint configuration the following parameters:

{'EndpointConfigName': 'xxxx',
 'ProductionVariants': [{'VariantName': 'staging-endpoint',
   'ModelName': 'xxxxx',
   'ServerlessConfig': {'MemorySizeInMB': 2048, 'MaxConcurrency': 2}}]}

but now I get this error:

ClientError: An error occurred (ValidationException) when calling the CreateEndpoint operation: One or more endpoint features are not supported using this configuration

Why I can't create a serverless sagemaker endpoint anymore ?

Thank you for using AWS SageMaker.

With the details provided, I see the parameters provided to the Endpoint Configuration are valid. To better understand the issue, I did try creating serverless endpoint under my account and I purposely created under a region where the Serverless endpoint is not supported i.e under us-west-2 and encountered same error as your, but same configuration worked under us-east-1 as it is supported. I'd recommend you to visit AWS documentation for [Serverless Inference] (, to verify if you are creating the Serverless Endpoint in supported region.

If the region is supported and you still face the issue, I'd recommend you to reach out to AWS Support for further investigation of the issue:
