Hello, I currently do this in version 0.85.0 and I get the error Network request failed.

The image are

  name: 'IMG-20251203-WA0008.jpg',
  type: 'image/jpeg',
  uri: 'content://...' or 'file://...
}

const formData = new FormData(); 

formData.append('content', data.content); 
data.images.forEach((e, i) => formData.append('images', e));

const response = await fetch('url', { 
  method: 'POST', 
  body: formData, 
});

formData.append('content', data.content);

No response

Commencez par exécuter le reproducer obligatoire et inspectez l’appel fetch qui envoie un FormData contenant des URI d’images sur Android. Suivez le chemin réseau de React Native utilisé par cette requête et comparez son comportement avec l’erreur signalée Network request failed. Le travail est terminé lorsque le reproducer peut téléverser les images avec succès sur React Native 0.85.0.
