HTTP POST request failing specifically on Android

Expo SDK
1

Please provide the following:

  1. SDK Version: 42
  2. Platforms(Android/iOS/web/all): Android

I am developing an iOS/Android app with React Native and I am getting an error on Android.

I am using the expo-image-picker library ImagePicker - Expo Documentation

This is the code which works perfectly on iOS and not on Android:

    const prepareResult = await ImagePicker.launchImageLibraryAsync({
      quality: 0.5,
      capture: true,
      aspect: [4, 3],
      allowsEditing: true,
      allowsMultipleSelection: false,
      mediaTypes: ImagePicker.MediaTypeOptions.Images,
    });

    const androidResult = await ImagePicker.getPendingResultAsync();
    const result = androidResult?.length ? androidResult[0] : prepareResult;

    if (!result.cancelled) {
      const localUri = result.uri;
      const filename = localUri.split("/").pop();
      const match = filename ? /\.(\w+)$/.exec(filename) : "";
      const type = match ? `image/${match[1]}` : `image`;
      const formData = new FormData();
      formData.append("file", { uri: localUri, name: filename, type });

      fetch(`${API}/uploadAvatar`, {
        method: "POST",
        headers: {
          Authorization: bearer,
          "X-Requested-With": "XMLHttpRequest",
          "Content-Type": "application/json",
        },
        body: formData,
      })
        .then((response) => response.json())
        .then((json) => {
          setImage(json.file);
        })
        .catch((err) => {
          console.log({ err });
          Alert.alert("There was an error uploading your profile picture.");
        });
    }

On Android after I crop the image, it goes straight to the .catch method without even going through any of the .then methods.

I checked this https://docs.expo.dev/versions/latest/sdk/imagepicker/#imagepickergetpendingresultasync which contains a note:

Note: Make sure that you handle MainActivity destruction on Android. See ImagePicker.getPendingResultAsync.

Any ideas about this error?
