Ambassador manipulates/changes json data types when forwarding to pods #3161

Describe the bug when ambassador api gateway forwards json body to pods , it manipulates/ changes json data types .

To Reproduce Steps to reproduce the behavior: when following request is made to eks with ambassador as gateway curl --request POST 'http://localhost:9000/predict' --header 'Content-Type: application/json' --data-raw '{"data":{"ndarray":[{**, "bbch": 10, ****}]}}'

when this body reaches to pods it is converted to following '{"data":{"ndarray":[{**, "bbch": 10.0, ****}]}}'

basically int is converted to float in json body.

Expected behavior data type manipulation should not happen.

Versions (please complete the following information):

additional info : NOTE : i am very new to ambassador and seldon . please ask for more details if needed and please provide relevant commands to produce that details if necessary.

not sure if it's related, but in my case, POST requests body data is dropped completely. Post requests were working fine before I've added a payload. And if I make requests via port-forwarding to a service, it works as expected. Also, I can see request body in dev tools, but my backend reports empty form data when request comes via ambassador (installed via helm chart version 6.6.2)
