Bytes parameter in rekognition throws "Request has invalid image format" error

Node version: v8.11.3 Npm version: 6.4.1 SDK version: 2.335.0

Bytes parameter not recognizing base64 encoded string “image/png;base64,Qk02EA…” and throwing error “InvalidImageFormatException: Request has invalid image format” when i try to make the request. I also tried with:

• Buffer
• Blob
• Typed Array

They all display the same error. Test case:

let params = {
   Image: {
     Bytes: 'BASE_64_STRING'
   },
};

rekognition.detectFaces(params, function(err, data) {
    if (err) {console.log(err, err.stack)}
    else console.log(JSON.stringify(data);
});

Can you give an example of how you are setting up the Bytes (or Buffer, Blob, Typed Array)?

This Buffer example should work for you:

const fs = require('fs');
const file = 'foo.jpeg';
const bitmap = fs.readFileSync(file);
const buffer = new Buffer.from(bitmap, 'base64')

let params = {
   Image: {
     Bytes: buffer
   },
};

Could you also try using uploading the same image to the Rekognition Console?
