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.

And its in private beta so if you use it in production that's at your own risk

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?

A binding enables your Pages Functions to interact with resources on the Cloudflare developer platform. Use bindings to integrate your Pages Functions …

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

export async function onRequestGet(context) {

}

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

export async function onRequestGet(context) {

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

regular functions invokation without url param like

/function?testing=1234

/function?testing=1234

/function?testing=1234

/function?testing=1234 works fine for starting the worker
but when i do add the url param, it doesnt work.

Since a couple of days my DO keeps throwing this error when running

puppeteer.launch(this.env.BROWSER))

puppeteer.launch(this.env.BROWSER))

puppeteer.launch(this.env.BROWSER)).

Unabled to create new browser: code: 429: message: Too many browsers already running

Unabled to create new browser: code: 429: message: Too many browsers already running

I don't seem to be able to reset this. I have tried to force kill the DO with

state.blockConcurrencyWhile(() ={ throw new Error("Intentional crash")) }

state.blockConcurrencyWhile(() ={ throw new Error("Intentional crash")) }

state.blockConcurrencyWhile(() ={ throw new Error("Intentional crash")) }

state.blockConcurrencyWhile(() ={ throw new Error("Intentional crash")) } in the constructor, but even that doesn't help.

Is there any way I can take control of the situation and reset the browser state or something?

The browser runs on a 3 minute cron job and has been working flawlessly for several weeks, until it suddenly stopped working a little while back. I don't know exactly when because I don't have good logging set up for this function.
