Unable save large file to S3 using Parse server - ios

Question

I tried to save to S3 bucket using Parse Server, and it can be saved correctly when the file is small, such as 864.2KB. However, when the file is large, say 5MB, it complaints with a message saying: "The data couldn’t be read because it isn’t in the correct format"
I'm using the following code to save the the video file to the S3
func saveVideo(withVideoURL url: URL){
let post = PFObject(className: "Post")
post["caption"] = "Out of the game for 6 months, but back with vengeance. Meet your 2017 AO Men's champion"
do{
let data = try Data(contentsOf: url)
print(data)
post["media"] = PFFile(data: data)
post.saveInBackground { (success, error) in
if success{
print("video saved")
}else{
print("failed")
if error != nil{
print(error!.localizedDescription)
}else{
print("erorr is nil")
}
}
}
}catch let error as NSError{
print("can't read")
print(error.localizedDescription)
}
}
Besides, even when the small video file is indeed being saved to the S3, it contains an extension .bin instead of, for example .mp4. I wonder what's happening here
The url end up looking something like this
https://s3-us-west-1.amazonaws.com/sampleApp/19d5bce20f8b55te1b1b8f370212533e5_file.bin

Answer 1

You need to stipulate the content type. You can do so like this:
post["media"] = PFFile(data: data, contentType: "video/mp4")

Answer 2

The below settings in your parse-server index file will help you:
var bodyParser = require('body-parser');
app.use(bodyParser.json({limit: '20mb'}));
app.use(bodyParser.urlencoded({limit: '20mb', extended: true}));
If you are using elastic beanstalk, you have to have a file named files.config inside the folder .ebextensions, with the below content.
files:
/etc/nginx/conf.d/proxy.conf:
content: |
client_max_body_size 20M;
This fixed the issue for me.
