"list" argument must be an Array of Buffers

The following code is throwing an error “list” argument must be an Array of Buffers

speakeasy.hotp({ secret: 'ir6jqgomwnldmrhn', encoding: 'base32', counter: speakeasy._counter({}) })

I am doing this in an angular 5 app.

Solved, In “node_modules/speakeasy/index.js” replace from line 39 to 41 with this code

if (!Buffer.isBuffer(secret)) {
    secret = encoding === 'base32' ? new Buffer(base32.decode(secret)) : new Buffer(secret, encoding);
  }

In case anyone had an issues with this. I used @ygweric code more or less but here I added full code (with dependencies and toHex implementation). For base32 decoding, I used `hi-base32: “^0.5.0” in my package.json

const secret = "...."; // retrieved from server as string in base32

const base32 = require('hi-base32');
const secretAscii = base32.decode(secret);
const secretHex = toHex(secretAscii);
const totp = speakeasy.totp({secret: secretHex, encoding: 'hex'});

function toHex(str) {
    let result = '';
    for (let i = 0; i < str.length; i++) {
        result += str.charCodeAt(i).toString(16);
    }
    return result;
}
