Description
Apologies if this is a question rather than a bug - I don't know where else to seek help.
I’m trying to implement an app similar to the O’FISH app. I followed the tutorial to the letter. My images are temporarily stored as binary data in MongoDB before being sent to S3 via a Realm trigger function.
I’ve written a realm function that uploads a file to my S3 bucket. This function works fine if the file is "hello world". However, I get Error: Unsupported body payload object when my file is a binary image queried from a MongoDB document.
How do I upload a binary image (straight out of a MongoDB document) to S3? Do I need to change the format my images are in?
Stacktrace & log output
No response
Can you reproduce the bug?
Yes, always
Reproduction Steps
Here is my realm function:
var drawings = context.services.get("Cluster0").db("databaseName").collection("drawings"); // get drawing document const query = { "_id": BSON.ObjectId("61c348229f2368fd6f2a2f95")}; const projection = { "_id":1, "thumbnail" : 1, } drawings.findOne(query, projection) .then(doc => { const imageName = doc._id.toString() // THE UPLOAD TO S3 WORKS WITH LINE BELOW // const file = 'hello world' const file = doc.thumbnail console.log('file type', Object.prototype.toString.call(file)) // this logs: [object Binary] // call uploadImageToS3 function context.functions.execute("uploadImageToS3", imageName, file) .then (() => { console.log('Uploaded to S3'); }) };
And here is my uploadImageToS3 function:
exports = async function(imageName, file) {
const AWS = require('aws-sdk');
AWS.config.update({
accessKeyId :context.values.get("AWS_ACCESS_KEY_ID"),
secretAccessKey : context.values.get("AWS_ACCESS_KEY_SECRET"),
region: context.values.get("AWS_REGION")
});
const s3 = new AWS.S3({apiVersion: '2006-03-01'})
const bucketName = context.values.get("AWS_BUCKET")
return s3.upload({
"Bucket": bucketName,
"Key" : imageName,
"Body": file,
"ACL": "public-read",
"ContentType": "image/jpeg",
}).promise()
}
