I am using AWS Sagemaker to host an asynchronous endpoint.
I have a custom inference.py code for this task.
This is how i invoke the endpoint using boto3:
response = client.invoke_endpoint_async(
    EndpointName='string',
    ContentType='string',
    Accept='string',
    CustomAttributes='string',
    InferenceId='string',
    InputLocation='string',
    RequestTTLSeconds=123,
    InvocationTimeoutSeconds=123
)
I use https://github.com/aws/sagemaker-huggingface-inference-toolkit to custom the endpoint.
However, I have a question that: where can I access the CustomAttributes. in sagemaker-huggingface-inference-toolkit?
Any help is appreciated. Thanks
