Browser Rendering Env Binding in local dev is not set?

In my local wranger dev I can see logs saying it will bind browser but when I print out env from fetch or queue param its undefined. I assume it's why I am seeing this error trying to launch puppeteer.

const browser = await puppeteer.launch(env.CRAWLER_BROWSER);

const browser = await puppeteer.launch(env.CRAWLER_BROWSER);

✘ [ERROR] TypeError: Cannot read properties of undefined (reading 'fetch') at PuppeteerWorkers.launch

Oh its not supported in local

Local mode support does not exist for Browser Rendering so --remote is required.

https://developers.cloudflare.com/browser-rendering/platform/wrangler/ But doing --remote breaks queues

▲ [WARNING] Queues are not yet supported in wrangler dev remote mode.

So I can't use queues and browser together 😦
