Difficulty Setting up with NextJS

super excited about the launch on vercel! however

I keep getting the following errors when I try to launch on localhost:

I'm following the NextJS setup guide. https://www.rivet.dev/docs/actors/quickstart/next-js/

this is my setup:

import { actor, setup } from 'rivetkit';

import { aiAgent } from './actors/ai';

export const counter = actor({
  state: { count: 0 },
  actions: {
    increment: (c, x: number) => {
      c.state.count += x;
      c.broadcast('newCount', c.state.count);
      return c.state.count;
    },
  },
});

export const registry = setup({
  use: { counter },
});

import { actor, setup } from 'rivetkit';

import { aiAgent } from './actors/ai';

export const counter = actor({
  state: { count: 0 },
  actions: {
    increment: (c, x: number) => {
      c.state.count += x;
      c.broadcast('newCount', c.state.count);
      return c.state.count;
    },
  },
});

export const registry = setup({
  use: { counter },
});

when I access http://localhost:3000/api/rivet/actors?namespace=default

I get

Not Found (RivetKit)

Not Found (RivetKit)

but when I access /metadata I get

"runner": {
"kind": {
"serverless": {}
}
},
"actorNames": {

}
},
"clientEndpoint": "http://localhost:6420"
}

{

}
},
"actorNames": {

}
},
"clientEndpoint": "http://localhost:6420"
}

I'm using turborepo if that matters.
