Is that just by running the constructor

 try {
      const characterStub = await getAgentByName<Env, CharacterAgent>(
        c.env.CharacterAgent,
        name,
      );

      return await characterStub.onRequest(c.req.raw);
    } catch (e: any) {
      return c.json({
        success: false,
        error: e.message,
      });
    }

 try {
      const characterStub = await getAgentByName<Env, CharacterAgent>(
        c.env.CharacterAgent,
        name,
      );

      return await characterStub.onRequest(c.req.raw);
    } catch (e: any) {
      return c.json({
        success: false,
        error: e.message,
      });
    }

  onRequest(request: Request): Response | Promise<Response> {
    console.log('got request:', request);
    return new Response('Hello from Agent!');
  }

  onRequest(request: Request): Response | Promise<Response> {
    console.log('got request:', request);
    return new Response('Hello from Agent!');
  }
