Is there any updated example for using this? I keep getting

TypeError: Cannot read properties of undefined (reading 'fetch')

TypeError: Cannot read properties of undefined (reading 'fetch')

which is pretty useless without a stack trace, I do not have any

I'm facing the same issue. I've downgraded puppeteer fork to 0.0.1, but this same error.

[mf:err] TypeError: Cannot read properties of undefined (reading 'fetch')

Thanks, that fixed the error, but now a new error.

Shyam•7/29/23, 4:06 PM

does this mean that I can't use workers to generate a pdf yet? How other people are doing it?

does browser rendering api let you embed it on my web app from which user can interact with the remote browser?

Night bird•8/4/23, 9:28 AM

Do we have a limit on the number of API calls we can make once we are white listed? Is there any chance that you will revoke access? is it OK to use in production? @Skye

As this feature is in Beta I think you have to make your own risk assessment to know if it is ok to use it in production.

sty•8/6/23, 10:33 AM

Im wondering the same thing. Any luck getting it to work in functions?

sty•8/6/23, 10:40 AM

so service binding is the only viable method right?

export async function onRequestGet(context) {
  return context.env.SERVICE.fetch(context.request);
}

export async function onRequestGet(context) {
  return context.env.SERVICE.fetch(context.request);
}

if i use service binding and i pass data thru the url param. i get this error

      "name": "TypeError",
      "message": "Failed to construct 'Response': constructor parameter 2 is not of type 'InitializerDict or Response'.",

sty•8/6/23, 5:30 PM

regular functions invokation without url param like /function?testing=1234/function?testing=1234 works fine for starting the worker
but when i do add the url param, it doesnt work.

@Vero

good time of the day. is there a way to get ~10 pages rendered via BROWSER, should we batch the workloads? imo 2rpm is quite limiting for testing

, is it possible to cache/reuse browser instance?
