Unnecessary Error Message Prefix in API Responses

[takhyun12]

Hello,

I am using bentoml.exceptions such as UnprocessableEntity in the following way when an error occurs in the service.api:

@service.api(
    input=Multipart(data=File()),
    output=Image(),
    route="/inpaint/v1/wrinkles",
)
async def api(data: BytesIO):
    (...)
    if not face_masks:
        raise UnprocessableEntity(message="No face detected")

However, I noticed that the error message appears in the following format:

"BentoService error handling API request: No face detected"

I believe that exposing the serving framework in the error message is unnecessary, and I would like to remove the prefix such as BentoService error handling API request. I only want the JSON-formatted message to be returned to the client.

I have tried various approaches mentioned in the BentoML exceptions documentation but have not found a way to achieve this. It seems like it might be due to the way it's implemented in the following code.

Could you please advise if there is a way to resolve this issue?

Thank you in advance for your assistance!

This is mainly the server log. If you want to return a JSON response to the client they it is probably better to return a JSONResponse, or a pydantic model for error
