Proc get convert some character in url and api doesn't work

[MauGal]

I have an url that is similar to this:
https://address_api/users/?fields=name&filter[code]=xx

With HttpClient works perfectly

Using puppy I have an error.
Url is converted:
https://address_api/users/?fields=name& amp ;filter%5Bcode%5D=xx
& amp ; without spaces
and the api response with a 302 code
