Note: the above is an example from the docs and not my code (links not configured etc)

railway is a headless environment, so I'd say no its not going to be supported

Oh I see, thanks

Any idea if I can load a stream from a wss in headless mode?

I don't see why not, I also don't see how headless or not would come into play here

The stream I'm trying to load is from my own app - and can change the page I'm visiting with puppeteer

Hm I see, I can't get the wss to load for some reason

How I know the stream isn't loading

const targetWsUrl = "wss://url/rtc";
  let wsConnected = false;

  page.on("request", (request) => {
    console.log("Request:", request.url());
    const url = request.url();
    if (url.startsWith(targetWsUrl)) {
      wsConnected = true;

hmmm, I don't really know what to tell you here

Any args for me to run that you think might help maybe?

sorry, I don't have any real experience with puppeteer

Okie, thanks anyways :)

@Brody is there any other way you know of to run Browserless in headful mode?

well does something error out when you tell it to run with a head?

It works fine in headful, only issue is with headless

Which it turns out WebRTC streams aren't supported in headless mode

right but can you not run it in headfull mode?

Correct

then there you have it

I also noticed you are using browserless.io, instead of self hosting browserless on railway? not that it would fix anything

Oh I'm using the Railway instance - I just copied that off their docs

ah okay cool

Out of curiosity, why doesn't Railway support headful mode?

it's a docker environment, there are no heads, nothing specific to railway

Oh I see, so if I added something like x11 into the container it would work?

yeah, you'd need to emulate something like that

if you give me several hours, i may be able to implement that for you

Oh!!

I would super super appreciate that

id just need you to provide me with a minimal reducible example that i can run so that tells me / shows me that ive started chrome in headfull mode, of course this example should also provide some indictor or error if i try to start chrome in headfull mode and browserless isnt supporting that, know what i mean?

Sure let me work on that

i say several hours because im just about to head out, so ill work on it when im back

but that gives you time to work on the example!

Works perfectly, thanks a bunch :)

no problem!

mind throwing that in a repo so I can simply run it in a service?

Sure!

full repo that has everything I'd need to trigger that code to run and do it's thing

What's your github?

brody192

Done, just sent over the repo to you

it doesn't look very minimal

I guess it does crash when headful is unsupported while requesting it in the .connect

Will update

Done, just pushed the simplified version

haha I think you are missing the point of minimal

Ok I might be 😭

What do you mean by it?

not a full project, just like a single script that proves the issue / proves it's fixed

Oh, I thought of doing that but wasn't sure how it would be trigerred on Railway easily

so I resorted to the existing

you'd have your package.json setup properly, right now you have a full app

Sorry about that, want me to rewrite it?

I'd just like a minimal reproducible example, emphasis on minimal

Done, just pushed it

okay perfect, now that's minimal

one question, how have you been able to verify that this code works? run it with your local chrome install instead of browserless?

Yes, I wrote it with normal puppeteer initially and then modified it for browserless

Will test it out again with the minimal version

okay perfect

Seems like there's an issue with some newer updates I made to it, let me fix and push

Okay fixed - when you run local.ts it uses normal puppeteer, when you run index.ts it uses browserless

You'll be able to see the difference it output between the two (and sorry for the hassle - I should have tested the newest version with all the new stuff I added on while debugging)

(Headless always returns a blank screen)

okay cool, what version is going to run by default when deployed to railway?

The browserless version

perf

i dont have bun locally (windows without WSL) so how can i verify that this is not working?

how fast could you add in a web server to serve that image?

I can start the stream, and if the file size increases we'll know it's working

Uint8Array(4190) would increase?

Just a rough guess - let me get back to you on this

Yes it would

might help to have a web server to serve that image?

Okay let me see

i know i said minimal but id still need a way to verify my findings since i cant run this locally

Ofcourse - working on a webserver to serve the image

web server or convert to plain old node, whatever is easier

Pushed

sweet

http://{domain}/thumbnail/the_winzy

this was such a good feature

Oh I didn't even know that was a feature

W feature

yeah i mean in this scenario i trust what you are pushing but its a good security feature to have

Yeah 100%

and you said if the image is black its not working?

Correct

If it's just all black and no text/icons

gotcha

Uint8Array(4190) should mean it's working as far as I can tell

But that's just a terrible way to check lol

thats funny since i didnt implement the virtual display server yet

Oh??

are you using browserless v1 or v2

v2

same

Ok we should probs see the result from the endpoint

waiting for dns to update so i can see the image

Nvm, I got mixed up - I have the stream running now so it should be easier to see if it works or not

dns still isnt updated yet lol

You'll see my screen if it's working or a black screen

Oh xD

it is indeed black

I rlly hope X11 fixes this

me too

<:prayge:1231933593924927560>

Thanks again for all the effort, super appreciate it

of course!

you are running it in headless mode? i thought you wanted headless false?

Ooops I forgot to change that back

Pushed

awsome

is the stream running?

Yep

still black even with xvfb running

:(

The browserless instance doesn't crash though while connecting with headless: false?

correct

sighs will have to dig in further tomorrow when I get up, almost 9 am for me

great sleep schedule lol

can you leave the stream running?

Could you share an easy way for me to replicate the instance with headful mode on?

For sure

this is what ive done so far

it works now, and all i did was switch to browserless v1.

stock template, no xvfb.

Interesting - no idea why that works but, thank you so so much

Literally saved me from another few days of debugging :)

no problem!
