When running the following code I keep getting a type error of

readable is not async iterable

readable is not async iterable

, I narrowed it down to the

const pdf = await page.pdf();

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

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")) }

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.

Running Serverless Puppeteer with Workers and Durable Objects

We’ve heard from developers that configuring and maintaining their own serverless browser automation systems can be quite painful. The Workers Browser Rendering API solves this

Is the concurrent session pricing based on the peak concurrency during the month or do you have to pre-pay a set concurrency limit (and can you set a concurrency limit if it’s the first option?)

M

Mackenly•9/28/23, 5:06 PM

And is that $1 each time you spawn a concurrent session or is that per month based on peak?

M

Mackenly•9/28/23, 6:08 PM

Wouldn't it be more cost effective to just keep a DO with a session alive perpetually? It costs just over $4 to keep a DO alive all month. If you use browser rendering just twice a day you're at $6/m (60*$0.10) in session costs. Setup a queue to process requests handled by that single DO and you never have to worry about having more than one session for an entrire month, correct?

A

Advany•9/28/23, 6:37 PM

I also dont get the pricing. Would be great to get insights

Hhannes Same question about 10cent session price.. is this per spawned session? How does...

U

Unsmart•9/28/23, 6:56 PM

The per session would be every time you call

puppeteer.launch()

puppeteer.launch()

. You can reuse the session as explained with DOs in the blogpost which would make it where you can pay per minute with only the initial request warming up the DO costing or anytime the DO gets reset (should mostly code updates / runtime updates)

A

Advany•9/28/23, 7:07 PM

So then keeping do alive would be cheaper right?

U

Unsmart•9/28/23, 7:11 PM

depends on your usage levels

M

Mackenly•9/29/23, 5:40 PM

From my understanding it would just be $0.10 every time the DO and browser session is instantiated as long as it's kept alive, so not even every day, as long as the browser instance gets a command at least every 60 seconds. If this is as it seems the pricing really doesn't make sense. Either there's an undocumented time limit on session time or the session pricing should be much lower to incentivize users to create new sessions rather than keep one open. Paying $0.10 once feels like a loophole.

If the best practice is to leave a session open, that should definitely be communicated in the pricing/docs since without considering using a DO, the pricing seems super high (who could justify $0.10 to take a screenshot when you can do the same thing with puppeteer on GCP functions or AWS for much much less).

U

Unsmart•9/29/23, 8:21 PM

requests != sessions

U

Unsmart•9/29/23, 8:23 PM

but also 50 sessions would only be $5

C

captain•9/30/23, 5:09 PM

hey guy's made the request to get into this a while back...i even run a server using pupperteer as part of a workflow process...would love to start playing with this...been developing in workers for 2 years...any updates now that its in beta in getting access to this?

D

DanTheGoodman•10/6/23, 4:27 PM

How does the concurrent session pricing work? Do I pay $1 to have the ability to run 2 sessions concurrently per month? (se then I can pay $5 for a concurrency of 6) Or is it $1 instead of $0.1 if there is already a session working? The blog post wasn't clear on that.

A

Aaron Peters•10/9/23, 11:57 AM

The pricing is confusing to me too.
What do I pay if I have one browser instance running all the time and it's constantly doing work (e.g. take screenshot of a page, one after the other .. all the time)
As I read it, that is one browser instance and one (concurrent) session, so the costs are 0 as the Workers paid subscription includes 500 Sessions and 10 Concurrent Sessions. Is this a correct understanding?
