  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, 
});

No response

Führe zunächst den obligatorischen Reproducer aus und untersuche den fetch-Aufruf, der auf Android FormData mit Bild-URIs sendet. Verfolge den von dieser Anfrage verwendeten React Native-Netzwerkpfad und vergleiche sein Verhalten mit dem gemeldeten Fehler Network request failed. Als erledigt gilt die Aufgabe, wenn der Reproducer die Bilder unter React Native 0.85.0 erfolgreich hochladen kann.
