Any log messages given by the failure

passing the mhtml file from my side show error saying ("raise HTTPError(http_error_msg, response=self) requests.exceptions.HTTPError: 500 Server Error: Internal Server Error for url: http://localhost:8080/rag/upload?rag_config=mhtml-vision-example") in the eval directory terminal and the api directory terminal show the error
"INFO: 127.0.0.1:50536 - "POST /rag/upload?rag_config=mhtml-vision-example HTTP/1.1" 500 Internal Server Error ERROR: Exception in ASGI application".

Expected/desired behavior

it should work correctly with our custom mhtml file also.
