useMutation stuck on loading and onComplete is not getting called - Expo React Native

Hi, I am building an Expo React Native App and when I use the useMutation hook the loading state is not updating and it gets stuck at true. Since it gets stuck on loading, the onComplete callback is not getting called.

loading: true
data: undefined

No errors coming from the server side.

Am I missing something?

Thank you for your help :slight_smile:


import { gql } from "@apollo/client";
export const SIGNUP_USER_TRACKING = gql`
  mutation SignupPatientSubmitAllowedTrackingSetting {
    signupPatientSubmitAllowedTrackingSetting {
      trackingSetting {


  const [signupPatientSubmitAllowedTrackingSetting, { data, loading, error }] =
    useMutation(SIGNUP_USER_TRACKING, {
      errorPolicy: "all",
      onCompleted(data) {

  const handleTracking = async (answer) => {
    try {
     await signupPatientSubmitAllowedTrackingSetting({
        variables: {
          trackingSetting: { allowTracking: answer },
          onboardingStage: "TRACKING_SETTING",
    } catch (e) {

  if (loading) return <Loader show={true} />;
  if (error) return console.log(`Submission error! ${error.message} `);

const httpLink = createHttpLink({
  uri: BASE_URL,

const authLink = setContext(async (_, { headers }) => {
  const token = await AsyncStorage.getItem("token");
  return {
    headers: {
      authorization: token ? `Bearer ${token}` : "" ,

  link: authLink.concat(httpLink),

There doesn’t seem to be anything obviously wrong with this.
Can you add a console.log("test") after the await signupPatientSubmitAllowedTrackingSetting(...)?
Does that execute?

Hi Lenz,
yes, it executes

So signupPatientSubmitAllowedTrackingSetting finishes. This seems very weird. Could you try to create a reproduction of this, maybe based on GitHub - apollographql/rn-apollo-client-testbed so I can take a look at this?

Hi Lenz,

finally I’ve managed to find the problem: the request is not being finished.

Timing tab:
CAUTION: request is not finished yet!

Here are the logs.

Great that you found it! Yeah, that’s something you’ll probably have to investigate on the server side then.
