Includes the inference provided by the model.
For information about the format of the response body, see Common Data Formats-Inference.
The MIME type of the inference returned in the response body.
Provides additional information in the response about the inference returned by a
model hosted at an Amazon SageMaker endpoint. The information is an opaque value that is
forwarded verbatim. You could use this value, for example, to return an ID received in
CustomAttributes header of a request or other metadata that a service
endpoint was programmed to produce. The value must consist of no more than 1024 visible
US-ASCII characters as specified in Section 3.3.6. Field Value
Components of the Hypertext Transfer Protocol (HTTP/1.1). If the customer
wants the custom attribute returned, the model must set the custom attribute to be
included on the way back.
The code in your model is responsible for setting or updating any custom attributes in
the response. If your code does not set this value in the response, an empty value is
returned. For example, if a custom attribute represents the trace ID, your model can
prepend the custom attribute with
Trace ID: in your post-processing
