`fetchToken` timing out

[Fruup]

Package: kontist@0.52.12

I'm getting a timeout when trying to fetch a token from an authorization code using the JS SDK. It looks like the specifics of the API changed without them being reflected in the SDK?

The Error

Error fetching token: Error

The following exception was the direct cause of the above exception:

const kontist = new Client({
  clientId: "***",
  scopes: ["transactions"],
  redirectUri: "http://localhost:3000/auth/callback",
  state: crypto.randomUUID(),

Bun.serve({
  port: 3000,
  routes: {
    "/": async (request) => {
      console.log(request.method, request.url);

      return Response.redirect(await kontist.auth.tokenManager.getAuthUri());
    },
    "/auth/callback": async (request) => {
      console.log(request.method, request.url);

      console.log("Callback received. Fetching token...");

      try {
        const token = await kontist.auth.tokenManager.fetchToken(request.url);
        console.log(token);
      } catch (error) {
        console.error("Error fetching token:", error);
        return new Response("Error fetching token", { status: 500 });
      }

      return new Response("😎");
    },
  },
});

console.log("Server is running on http://localhost:3000");
