Unmarshal request body fail should not panic

[tnclong]

Content-Type: application/json

{
	"codes": ["5S63204"
}

POST /api/ja/proto.ProductService/GetProducts -> 500 Internal Server Error (panic: invalid character '}' after array element)

Maybe 422 is more better?

Client said they were sending JSON (Content-Type header), but they didn't send valid JSON.
