[BUG] Unable to use playwright as of version 0.52.1, also present in version 0.52.6

[jluo98]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

A check cannot be completed using Playwright, error message:
Screenshot unavailable, page did not render fully in the expected time or page was too long - try increasing 'Wait seconds before extracting text'.

Changing the fetch method to the built-in HTTP fetcher results in no error (unless website requires JS)

This issue is not present in the official docker image provided by dgtlmoon

Expected Behavior

A check using playwright completes without error.

Steps To Reproduce

1. Set up a fresh instance of changedetection.io from lscr and browserless-chromium as the playwright server
2. Add a check of any website and configure it to use playwright
3. Run the check and the check would fail
4. Run the above steps with changedetection.io from dgtlmoon instead, no error occurs

Environment

- OS: Unraid 7.2.3

Can you test lscr.io/linuxserver/lspipepr-changedetection.io 0.52.6-pkg-ac12a80c-dev-3bb28f8c4697921628cd9b4901964bdd297aaf2a-pr-32 and see if it makes any difference?

It does not, unfortunately. Same error
Screenshot unavailable, page did not render fully in the expected time or page was too long - try increasing 'Wait seconds before extracting text'

OK that's fine, just means it's not an issue with using a newer version of Playwright than the upstream image.

Let me do some testing and see if I can replicate the issue locally.

[emeybee]

I am having the same issue FWIW. I just posted on the ChangeDetection Github, should I delete that one? dgtlmoon/changedetection.io#3783

My logs are here: https://pastebin.com/5C3h94tM

From my testing, the docker image provided by dgtlmoon does not have this problem, so it seems like an issue with the linuxserver image. I've switched over to the dgtlmoon image for now.

I tried that but the settings don't seem to store in appdata, so everytime the docker restarts it erases all of the settings. Not sure if I'm doing something wrong, I'm on Unraid. Hopefully Linuxserver gets it fixed quickly so it's a non-issue.

[jluo98]

the settings don't seem to store in appdata

The dgtlmoon image mounts the config folder in /datastore (instead of /config which the linuxserver image uses). You just need to change the container path to that and you should see your checks and settings.

Got it to work, thanks! Definitely on Linuxserver's side it seems.

Just wanted to chime in and say that I am seeing this exact issue. Changing image also worked here.
