iOS crashes when retrieving an image on a device using XMLHttpRequest

[dododoSA]

Description

The app crashes when I try to save the images I took to Firebase Storage. (This only happens on iOS)

After checking line by line using console.log, I found that the crash occurred at the point where XMLHttpRequest is used, as shown below.

Steps to reproduce

1. Create an expo app.
2. Start on iOS.
3. Get the uri of the photo taken by the file picker.
4. Save to Firebase Storage with the following code.

The app crashes when retrieving an image file as shown below.

      const blob = await new Promise<Blob>((resolve, reject) => {
        const xhr = new XMLHttpRequest();
        xhr.onload = () => {
          resolve(xhr.response);
        };
        xhr.onerror = (e) => {
          reject(new TypeError('Network request failed'));
        };
        xhr.responseType = 'blob';
        xhr.open('GET', values.imageUrl, true);
        xhr.send(null);
      });

      console.log('This log is not output. ')
      const avatarRef = ref(storage, path);
      await uploadBytes(avatarRef, blob, metadata); // from 'firebase/storage'

If you use setTimeout to delay the timing of resolve, it will work without crashing. (I am not sure why.)

      const blob = await new Promise<Blob>((resolve, reject) => {
        const xhr = new XMLHttpRequest();
        xhr.onload = () => {
          // changed here
          setTimeout(() => {
            resolve(xhr.response);
          }, 500);
        };
        xhr.onerror = (e) => {
          reject(new TypeError('Network request failed'));
        };
        xhr.responseType = 'blob';
        xhr.open('GET', values.imageUrl, true);
        xhr.send(null);
      });

      const avatarRef = ref(storage, path);
      await uploadBytes(avatarRef, blob, metadata); // from 'firebase/storage'

Still have the issue ... Can't believe we're the only two facing cause I would think that more people on expo try to upload media to firebase.

Closing as there is a follow-up issue in another repo. Moreover the mentioned RN version is really old. Would be worth trying on RN 0.69 and re-opening if the issue persists
