400 bad request on non encode query params

[popuguytheparrot]

there is http proxy middleware with CRA and axios

on the dev server, they are proxying to feature stands.

There is a problem that if you send a request in the form http://localhost:3000/api/customer/party/active?0=offset%3D0%26limit%3D15%26 then everything is OK, but if http://localhost:3000/ api/customer/party/active?offset=0&limit=15 then 400 bad request

from a postman to a feature stand, the request normally goes without encoding. Where to dig?
