[BUG] An internal error occurred during local development of remote browser rendering

[szxmsu]

Describe the bug

Here's minimal code and wrangler config may be related to the internal error:

const { env } = await getCloudflareContext({ async: true });
const browser = await puppeteer.launch(env.BROWSER, { keep_alive: BROWSER_KEEP_ALIVE });

  "env": {
    "development": {
      "vars": {
        // ...
      },
      "r2_buckets": [
        {
          "remote": true,
          "binding": "R2_BUCKET",
          "bucket_name": "shotify-files-development"
        }
      ],
      "browser": {
        "remote": true,
        "binding": "BROWSER"
      }
    }
  },

And the internal error is:

✘ [ERROR] Error: Unable to create new browser: code: 500: message: Error: internal error; reference = 9kfn1bbpprdndl2o6fcoguqn

Steps to reproduce

1. Run opennextjs-cloudflare build --env development && opennextjs-cloudflare preview --env development
2. Send an http post request to execute code await puppeteer.launch(env.BROWSER, { keep_alive: BROWSER_KEEP_ALIVE })
3. The internal error occurs after about 1.5 mins
