Node - "Unable to deserialize cloned data" when serializing multiple values

Question

I want to implement a custom serializer for my class so I can use it for networking. However, d.readValue throws an error: "Unable to deserialize cloned data."

Error: Unable to deserialize cloned data.
    at /home/runner/QuarrelsomeBurdensomeClick/index.js:7:15

const { Serializer, Deserializer } = require("v8");

let s = new Serializer();
s.writeValue("Abc");
s.writeValue("Def");
let d = new Deserializer(s.releaseBuffer());
console.log(d.readValue()); // Error here.
console.log(d.readValue());

Oddly, if one of the writeValue calls is removed along with a readValue, the code is run as expected.

How do I serialize multiple values without this error?
