Upload Video URI from React-Native Picker to AWS S3 Server - react-native

Question

I am trying to upload a video from my IOS device library to S3 using axios and a pre-signed url. I've determined the axios/s3 part is working great, but the issue is coming from the uri I receive from 'react-native-image-picker'.
When I record a video in react-native the video uri uploads fine in S3, but when I grab a video from my photo library it uploads to S3 but it's not a video file.
I grab the video uri from my ios device library using react-native-image-picker.
import {launchImageLibrary} from 'react-native-image-picker';
launchImageLibrary({mediaType: "video"}, ({assets}) => {
let {uri} = assets[0] //uri = /var/mobile/Containers/Data/Application/123/tmp/IMG_1779.mov
uploadFile(uri)
});
and then I attempt to upload the uri to S3
//save to s3 using presignedPost
uploadFile(uri){
var formData = new FormData();
...
formData.append("file", { uri });
await axios.post(presignedPost.url, formData,{ 'Content-Type': 'multipart/form-data' } )
}
The function is successful, but when I look in AWS the file is just a text file with a bunch of random characters.
The good news is this same exact uploadFile functions works if I record a video with react-native-camera
import { RNCamera } from 'react-native-camera';
stopRecord(){
let camera = cameraRef.current //grab camera <RNCamera ref={cameraRef} />
let {uri = null} = await camera.recordAsync(); //uri = /var/mobile/Containers/Data/Application/123/Library/Caches/Camera/123.mov
uploadFile(uri)
}
The only difference I can see is the uri after recording a video is stored in cache. Therefore, I attempted to use 'react-native-fs' to grab the picker uri, save it to cache, and then upload the cached file but I got the same error (file uploads to s3 but not a video).
import * as RNFS from 'react-native-fs';
uploadFileTwo(uri){
let base64Data = await RNFS.readFile(uri, 'base64')
let cachePath = RNFS.CachesDirectoryPath + "/" + fileName + ".mov"
await RNFS.writeFile(cachePath, base64Data, 'base64')
var formData = new FormData();
...
formData.append("file", { uri: cachePath });
await axios.post(presignedPost.url, formData,{ 'Content-Type': 'multipart/form-data' } )
}
So now I am out of options. Why would the 'react-native-camera' uri work great, but the 'react-native-image-picker' uri doesn't?

Have a try by following the Tutorial for uploading video file.
I think this tutorial meets all your requirements as it uses react-native-image-picker to upload the video file(s).
