How to reproduce the issue:
Create two links and use this code to switch between them:

const splittedHttpLink = split(

    return operation.operationName === "refreshToken";
  },
  httpLink,
  batchHttpLink
);

@itxtoledo can you share what your refreshToken query looks like?

[itxtoledo]

@hwillson

export const REFRESH_TOKEN_MUTATION = gql`
  mutation RefreshTokenMutation($token: String!, $refreshToken: String!) {
    refreshToken(token: $token, refreshToken: $refreshToken) {
      token
      refreshToken
    }
  }
`;

In the example i using this mutation but in all console.logs the operationName field is coming undefined

Hello ! I encounter similar issues on every request coming from my ApolloClient. What is the status of this ?

const response = await apolloClient.mutate({
      mutation: gql`
        mutation doSomething($foo: String!) {
          doSomething(foo: $foo) {
            outcome
          }
        }
      `,
      variables: { foo: '' },
    });

leads to a body received as follows server side:

{ "query": "...", "variables": { "foo": "" } }
