await puppeteer.launch(this.env.MYBROWSER); for a "normal" puppeteer for local testing? I'm aware that wrangler dev --remote should be used ,but this causes other problems (e.g. that queues are not working there and durable objects seem to have issues for this env as well)Spuppeteer package doesn't launch (some node stuff is missing) it's working with connect to services like browserless. Think that's good enough for me right now. Gonna see if there's some opensource version of a websocket server for puppeteerSwrangler dev this.browser = await puppeteer.connect({ browserWSEndpoint: ws://localhost:3000 });

Thanks a lot.S

And I had to switch to use the compatibility_flagsA
Trace resource limit exceeded; subsequent logs not recorded.. I'm guessing if you're doing browser stuff, you probably need to switch your worker types to unbounded?AAAMedian CPU Time 51.7 ms so will switch this one to unbound, ty!A And I can't for the life of me find it anywhere in the dashboard!A
ABuffer is not defined, which is a bit odd (same for .text() and .json()):pages.on was behaving very strangely so gave this a whirl insteadAcompatibility_flags = [ "nodejs_compat" ] in my wrangler.toml)A

UA So it looks like it's a problem with the CF fork, which I figured made sense considering the error was related to a Node library not being availableA

compatibility_flags = [ "nodejs_compat" ] in my wrangler.toml file.

CZZZtext: 'workers.api.error.no_access_to_browser_worker [code: 10088]' I guess this is due to gating by the API beta access, correct?CCSS
