Sharing: UE5 RpcUpdateMetadata

Client Libraries
1

In case anyone else needs to update metadata for the account in UE blueprints, I managed it using VaRest:

And, the server code (Typescript) file update_metadata.ts:

let rpcUpdateMetadata: nkruntime.RpcFunction = function (ctx: nkruntime.Context, logger: nkruntime.Logger, nk: nkruntime.Nakama, payload: string): string {
    if (!ctx.userId) { throw Error('No user ID in context'); }
    if (!payload) { throw Error('Payload expected.'); }

    let metadata = null;
    try {
        metadata = JSON.parse(payload);
    } catch (error) {
        logger.error('Error parsing: %q', error);
        throw error;
    }

    let username = null;
    let displayName = null;
    let timezone = null;
    let location = null;
    let langTag = null;
    let avatarUrl = null;

    try {
        nk.accountUpdateId(ctx.userId, username, displayName, timezone, location, langTag, avatarUrl, metadata);
    } catch (error) {
        logger.error('Could not update account: %q', error);
        throw error;
    }

    return JSON.stringify({});
}

Also, make sure to edit your tsconfig.json to add “./update_metadata.ts” to the “files” array.

And, in main.ts update to:

...
const rpcIdUpdateMetadata = 'update_metadata_js';

function InitModule(ctx: nkruntime.Context, logger: nkruntime.Logger, nk: nkruntime.Nakama, initializer: nkruntime.Initializer) {
   ...
   initializer.registerRpc(rpcIdUpdateMetadata, rpcUpdateMetadata);
   ...
}
