[Bug]: `puppeteer.limits` throws an error when used inside a durable object

[benank]

Minimal, reproducible example

Steps to reproduce:

1. Set up the browser rendering example from here.
2. Add this line inside the durable object's fetch method:

let limits = await puppeteer.limits(this.env.BROWSER);

3. Deploy the worker and trigger it using an HTTP request.
4. Observe that you get this error:

TypeError: endpoint.fetch is not a function at PuppeteerWorkers.limits

The limits method works as expected when used within a worker. However, when inside a durable object, it fails and throws an error.

Error string

TypeError : endpoint.fetch is not a function at PuppeteerWorkers.limits

Background

No response

Expectation

I am expecting the limits function to run and tell me the current browser rendering limits on my account so that I can wait if all my limits are used up before connecting to a browser in my durable object.

Reality

It throws an error when calling the limits function inside a durable object.
