I am trying to upload an image to my DigitalOcean Spaces using the Expo Image Picker and AWS SDK, but I keep encountering this error:
ERROR Error uploading image: [TypeError: Network request failed]
Here’s the relevant code that I’m using to upload the image:
import axios from 'axios';
import * as ImagePicker from 'expo-image-picker';
import { S3Client, PutObjectCommand } from '@aws-sdk/client-s3';
import 'react-native-get-random-values'; // This polyfills crypto.getRandomValues
import { v4 as uuidv4 } from 'uuid';
import { spaces } from '../config/digitalOcean';
import 'react-native-url-polyfill/auto';
import { ReadableStream } from 'web-streams-polyfill';
globalThis.ReadableStream = ReadableStream;
export default function AddItems({ navigation }) {
const [produceName, setProduceName] = useState('');
const [quantity, setQuantity] = useState('');
const [price, setPrice] = useState('');
const [itemImage, setItemImage] = useState('');
const [phoneNumber, setPhoneNumber] = useState('');
const [uploading, setUploading] = useState(false);
const s3Client = new S3Client({
endpoint: spaces.url,
forcePathStyle: false,
region: "blr1",
credentials: {
accessKeyId: spaces.spacesKey,
secretAccessKey: spaces.spacesSecret
}
});
useEffect(() => {
const loadPhoneNumber = async () => {
try {
const storedPhoneNumber = await AsyncStorage.getItem('phone');
if (storedPhoneNumber) {
setPhoneNumber(storedPhoneNumber);
} else {
Alert.alert('Error', 'Phone number not found');
}
} catch (error) {
console.error('Error loading phone number from AsyncStorage:', error);
}
};
loadPhoneNumber();
}, []);
const pickImageAsync = async () => {
let result = await ImagePicker.launchImageLibraryAsync({
allowsEditing: true,
quality: 1,
});
if (!result.canceled) {
uploadImage(result.assets[0]);
} else {
alert('You did not select any image.');
}
};
const getImageBlob = async (uri) => {
const response = await fetch(uri);
const blob = await response.blob();
return blob;
};
const uploadImage = async (imageAsset) => {
setUploading(true);
const fileName = `${uuidv4()}.jpg`;
try {
const response = await fetch(imageAsset.uri);
const blob = await getImageBlob(imageAsset.uri);
console.log("these happened without error")
console.log(response)
console.log(blob)
const params = {
Bucket: spaces.name,
Key: fileName,
Body: blob,
ACL: "public-read",
ContentType: 'multipart/form-data',
};
const data = await s3Client.send(new PutObjectCommand(params));
console.log(data)
const imageUrl = spaces.url + "/" + fileName
setItemImage(imageUrl);
Alert.alert('Success', 'Image uploaded successfully');
} catch (error) {
console.error('Error uploading image:', error);
Alert.alert('Error', 'Failed to upload image');
}
setUploading(false);
};
const handleSubmit = async () => {
if (!produceName || !quantity || !price) {
Alert.alert('Error', 'All fields are required');
return;
}
try {
const formData = {
phoneNumber,
itemName: produceName,
quantity,
price,
itemImage,
};
const response = await axios.post(
'myurl/api/supplier/add-item',
formData
);
if (response.status === 200) {
Alert.alert('Success', 'Item added successfully!');
navigation.goBack();
}
} catch (error) {
console.error('Error adding item:', error.response?.data || error.message);
Alert.alert(
'Error',
error.response?.data?.message || 'Failed to add item, please try again'
);
}
};
Since it is a expo app, in the cors settings i have used “*” as the domain name and enabled all methods (get,put,post etc). It is still giving the network error.

Hi there,
The Network request failed
error usually indicates a CORS issue or an incorrect endpoint. But it could also be a problem with how Expo handles network requests.
On the endpoint side, DigitalOcean Spaces uses https://{SPACE_NAME}.{REGION}.digitaloceanspaces.com
as the endpoint.
So your s3Client
should have forcePathStyle: false
and endpoint: 'https://blr1.digitaloceanspaces.com'
(or your region).
On the CORS front, even if you’ve set "*"
in CORS, double-check that it’s correctly applied in the Spaces settings under Manage Permissions → CORS.
As a quick test, try uploading an image using curl
or Postman to verify if Spaces is responding correctly.
