query parameter gets stripped from request payload

[isaacfink]

Hi guys, I have a really weird error when I try to perform a query the payload gets altered, and this results in a 400 error
this is my gql query

export const GET_CATEGORIES = gql`
  query {
    categories {
      name
      id
    }
  }
`;

and in the network tab this is how the payload looks like
query: {\n categories {\n name\n id\n __typename\n }\n}
I get an error saying [GraphqlQL] must provide query
