Data Plane API Error - "Not Found" when Retrieving Model Metadata

[anhquan075]

Describe the bug

When I try to use the Kserve Data Plane API in ModelMesh Serving to get the model metadata, an error with the code 5 and message "Not Found" is encountered.

{"code":5, "message":"Not Found"}

To Reproduce
Steps to reproduce the behavior:

1. Deploy a isvc
2. Port forward the modelmesh-serving service and send request to the route v2/models/${MODEL_NAME}[/versions/${MODEL_VERSION}]

Expected behavior

The expected behavior is to receive a response similar to Kserve in here with the following format:

$metadata_model_response =
{
  "name" : $string,
  "versions" : [ $string, ... ] #optional,
  "platform" : $string,
  "inputs" : [ $metadata_tensor, ... ],
  "outputs" : [ $metadata_tensor, ... ]
}

Screenshots
I created a example isvc using the mnist model

Upon sending a request to the route /v2/models/${MODEL_ID} (/v2/models/mnist-isvc), I received the following error message:

Environment (please complete the following information):

• OS: MacOS Monterey 12.6

Additional context
Are there any guides or suggestions available to help resolve this issue? My task requires retrieving model metadata such as input/output names and shapes.

This needs to be added to the rest-proxy, see kserve/rest-proxy#14
