Convert buffer to readable string javascript

I receive a JSON as a buffer. I want to parse it into a readable or JSON object.

However, despite all techniques (JSON.stringify(), toString('utf8'), I am not able to get it done.

here is what I have so far:

And here is what it gives me:

How can I transform it into a readable something?

If you are comfortable with hexadecimal representation of buffers use:

Buffer.from(val).toString('hex')

Try

console.log(Buffer.from(val).toString());

This will convert [object Object] as a string

Your code is working. The buffer you have is actually the string "[object Object]".

let b = Buffer.from('[object Object]', 'utf8')
console.log(JSON.stringify(b))
// {"type":"Buffer","data":[91,111,98,106,101,99,116,32,79,98,106,101,99,116,93]}

console.log(b.toString('utf8'))
// [Object object]

The problem you need to figure out is why is a buffer with that string being sent. It seems like the sender of the buffer needs to call stringify or otherwise serialize the object before sending it. Then you can turn it back to a string with toString() and use JSON.parse() on the string.
