Just seen the fail, something about it not liking the lack of a Kind instance for an EventBuilder. Will test it again in the morning, I'm pretty confident the code ran prior to the PR but am still juggling machines given that my Linux machine still doesn't like compiling the WebAssembly.Module().

Anyway will review and report back.

Curious, just re-tested this code and I have no issues running it locally (see image below, where the second JSON is the Tag build method)

@yukibtc would you mind running the following on your side and let me know if you have some issues. The book deployment checks seem to be falling over at EventBuilder with Error: expected instance of Kind, though from what I can tell this class takes a number for the kind argument, not a Kind class instance.

const { loadWasmSync, Keys, EventBuilder, Tag, RelayMetadata } = require("@rust-nostr/nostr");

function run(){
    // Load WASM
    loadWasmSync();

    // Generate Keys
    let keys = Keys.generate();

    // Create relay metadata tags
    let tag1 = Tag.relayMetadata("wss://relay.damus.io", RelayMetadata.READ);
    let tag2 = Tag.relayMetadata("wss://relay.primal.net", RelayMetadata.WRITE);
    let tag3 = Tag.relayMetadata("wss://relay.nostr.band", null);

    // Build/sign event
    let kind = 10002;
    let content = "";
    let tags = [tag1, tag2, tag3];
    builder = new EventBuilder(kind, content, tags);
    event = builder.toEvent(keys);

    // Print event as json
    console.log(` Event: ${event.asJson()}`);
}

run();

run();

The kind should be constructed in this way:

let kind = new Kind(10002);

I can fix it during cherry-picking

thanks! Got it sorted, weirdly it wasn't upgrading my package using the normal command. I was rocking v0.33. Had to uninstall the package and re-install the latest. Fixed it though now.
