This is what I did to try and make it work, but I just hit a wall, please note these ENV are per browserless's documentation

I took a look on the /sessions page to see what endpoint it was using and it uses:

Plus I am getting this also

I'm gonna try adding the env vars to the project specifically instead inside of the Dockerfile

you would need to get browserless to listen on :: or [::] aka ipv6

then you'd want to use it's private domain to connect to it from other services while on railway

Would I need to specific that as a HOST env?

unfortunately I am uncertain on how you would configure what host browserless runs on

for that, you would need to reference their documentation

Alright

Seems like it is just HOST as an environment variable

I assume you are using the browserless template?

Uh yes

Well I had to redeploy, but yes

that template is very old and thus made long before railway had private networking

you are not the first to have issues using it

Yes, but it uses the latest docker image

yes, but it's missing the correct configurations to use it

in fact it's so old, it deploys from a Dockerfile when it should be just a docker image without a github repository

[ghcr.io/browserless/base:latest](ghcr.io/browserless/base:latest) something like this?

I'll see if it works now

I don't know, did they stop hosting their images on dockerhub?

They still are

but they are also hosting on the github reg

any reason you decided to switch to the ghcr hosted image?

along with going for the base image and not the chrome image

oh I didn't I just sent what I saw on the ghcr

https://hub.docker.com/r/browserless/chrome

still on dockerhub

okay I switched from the template to the docker image directly

looks like you where correct about the HOST variable

Looks like it is not possible to supply "::" as a host value

here is the logs

just so you can see

have you tried the other host option I mentioned? [::]

uhh let me try

using [::]

interesting, though that is more progress

wonder why it's trying to do a DNS lookup on its own host?

yeah very good question… though it seems like some internal thing?

it needs to not do that lol

have you tried 0.0.0.0 as the HOST?

that is the default, but I will try and swap it to that

I thought 127.0.0.1 was the default, as your title says

well it looks like i was using v1 of browserless(which is what the template is using)

and after swapping to using the docker image directly

it swapped to v2

interesting, does this mean it works now?

logs now using default

okay good sign, no errors

other thing they also did was make a separate image for chormium

I was using the chrome image, which could also be why it does not connect

why would chrome Vs chromium cause it not to connect?

idk just reading the docs on the service said to swap it to use [ghcr.io/browserless/chromium](ghcr.io/browserless/chromium)

instead of [ghcr.io/browserless/chrome](ghcr.io/browserless/chrome)

idk what difference it makes

have you tried to connect to it yet?

yes

when I used the chrome specific image

and it still didn't work

what is the url you are trying to connect to it with?

so swapped to chromium image to see if that was the cause

ws://[browserless-production-9cdd.up.railway.app/playwright/chromium](browserless-production-9cdd.up.railway.app/playwright/chromium) as an external right now

you need to use wss

ah yeah

railway is ssl only

With connection tries

what is the url you are trying to connect to it with?

wss://[browserless-production-9cdd.up.railway.app/chromium/playwright](browserless-production-9cdd.up.railway.app/chromium/playwright)

please note

docs says it can take either way of that URL

could "PORT" be the issue here?

as I had it set to 3000

is that not the port browserless runs on?

uhh you can change it

with a env var

right but what's the default port browserless runs on

default is 3000

since I have set a external URL I can simply just try and connect to it with the generated URL

your url is incorrect, it was changed in v2 according to their migration guide

it should be /playwright/chromium

still says it can't see it

I'm gonna try with connectOverCDP

what's cdp?

no

sorry, typo

what the docs gives

ignoring ws as that should be wss

can't hurt to try

well that did nothing

as in no logs or anything

was worth a try

yeah idk why it keep saying it couldn't get that URL…

are you specifying a token?

nope

try doing so

with token

I'm at a loss of how to fix this

im trying some things, but i am going to leave the house soon so im not sure how much i will be able to get done

yeah that is alright, no rush on this

im not seeing how this is a limitation of railway, very likely just have some minor config wrong

yeah, its just odd

indeed

Funny.

I just tried running a websocket connect in Insomnium and it gets a 400…

what happens when you just open the /docs endpoint in your browser

This

I've been on it for a good while now

okay that at least works

I tried not having any proxy/external set as a env var as I had before

and I can still access this site without any issues

It's just so odd playwright wants to try and use some HTTP request?

and not just go straight to using websocket..

works fine for me

hmm……..

show me all your variables as shown in the raw editor

here are mine

and my url used in my code looks like wss:///playwright/chromium?token=

Okay let me try that out

are you using the docker image directly?

or the template

and remind me again, what is the current image you are using? im using [ghcr.io/browserless/chromium:latest](ghcr.io/browserless/chromium:latest)

that is the same as mine

i deployed all this from scratch

not that it would technically matter since at this point you are using the same image as me

I can do a full redeploy

and see what that does

show me your raw variables?

I did a redeploy with using the ghcr image link you sent

Just wondering if there would be a difference between these 2

for all intensive purposes, not specifying the :latest tag should be the same as specifying the :latest tag, but can't hurt to try

no difference

show me your code?

I'm using bun, but I don't think that should make an awful lot of a difference

oh bun, who knows, i've seen bun do some funky stuff

its still javascript so lets see the code anyway

Pretty much how it stands right now

Don't mind the top require one, I was just seeing if import and require had some quirky difference

but still same behaviour

would you be interested in trying their example code with node instead of bun?

always good to first get a minimal example working!

yeah let me spin up a minimal project then

huh…

that worked?

okay now run the same example code on bun?

ahaaa

<:ICANT:1010977143771111434>

so Bun just hangs when it tries to connect

while node does not

interesting…

thats running the same example code with bun?

guess that is a bun thing then

yes

and its just hanging

so this is a bun quirk

alrightly bun issue then

how fun

Just really pain for me

as I don't want to rewrite my whole project

you use bun apis?

Nope

None

besides bun run --watch

which is only locally

so then why would a rewrite be needed? just switch to node?

the production code is just running node dist/index.js

as I'm using tsup to compile(transpile) to js

right okay then its just something for local

good to know

I had it like this before

and I wanted to test browserless locally with bun

which then caused this mess

oh well

well problem solved though!

yes!

thank you for sticking with me 😂

and spending so much time on this

happy to help!

problem solved, and now you also have a v2 browserless deploy that can be used with node

Yes

the production command is node dist/index.js

so it doesn't rely on bun

time to change that token too!

ah yes true

feel free to close this issue now

I can't mark it as solved somehow

that seems like a good message to mark as solved haha
