How to convert the object of Uint8Array to string?

I have same problem as this question. I see the answer but I couldn't understand how I can do it. Is there any other suggestions?

My code is:

var eccrypto = require("eccrypto");
var w,actual;
var publicKey = Buffer.from([4, 86, 82, 58, 244, 11, 140, 41, 132, 245, 184, 162, 163, 98, 49, 119, 168, 235, 252, 50, 6, 91, 147, 191, 190, 61, 65, 63, 101, 164, 132, 213, 188, 106, 26, 203, 171, 215, 240, 151, 7, 193, 10, 151, 103, 107, 1, 135, 117, 225, 5, 41, 55, 57, 18, 205, 98, 178, 82, 135, 170, 111, 188, 98, 57],'hex');

var privateKey= Buffer.from([238, 239, 199, 101, 188, 134, 13, 13, 195, 172, 125, 168, 225, 189, 72, 148, 225, 200, 127, 218, 204, 11, 150, 146, 180, 243, 195, 109, 200, 119, 50, 20],'hex');

eccrypto.encrypt(publicKey, Buffer.from("message")).then(function(encrypted) {
    console.log(encrypted)

    let encoded =JSON.stringify(encrypted)
    w=encoded;
    console.log(encoded)

    actual = JSON.parse((encoded))
    console.log(actual)
});

eccrypto.decrypt(privateKey,actual).then(function(plaintext) {
    console.log("Message to part B:", plaintext.toString()); 
});

When I use actual variable I have this error: 

Uncaught (in promise) Error: Bad public key

this the output of encrypted :

this the output of encoded :

and this the output of actual "there is some things changes i think, is not it ?": enter image description here thank you advance.

While parsing, you need to send a reviver function, which conditionally parses the object. If you see how encoded looks, you will understand why the reviver function needs to be written this way.

I think you need to remove the "hex" encoding parameter from your Buffer.from.
