Deno npm:node-firebird won't work

[awunnenb]

Version: Deno 2.0.0

import * as Firebird from "npm:node-firebird";

let options = {};
options.host = "server.ip";
options.port = 3050;
options.database = "aDatabase";
options.user = "SYSDBA";
options.password = "password";

Firebird.attach(options, function (err, db) {
  console.log("in callback");
});

callbacks are never called!

with node.js or bun it works fine
