hmm, moved to discussion for now, i havent seen this at all, not even in the many paid instances we have what hardware are you running? "Parsing everything using the latest version of playwright." what does that mean exactly ? are you referring to the pip library or you mean the "browserless" docker container or? |

I was using selenium for these monitors before today but just switched to playwright to take advantage of the new Browser steps functionality that was released with v0.40.0.2, so its pretty fresh. Regardless, ive re-pulled a fresh image and theres no improvement. If you can suggest a different playwright version to pull, I can give it a try. |

Most of them came back alive. Indeed, something changed from 0.39 to 0.40 which leads to this error if 'wait seconds before extracting text' is set for high enough value |

Had the same issue since updating to v0.40.0.0/2 with all my URLs. There were no issues before the v0.40 version Seems to have fixed it by using the "Clear Snapshot History" button in settings. Will monitor and report back if the issue comes back Here is my docker run command: docker pull dgtlmoon/changedetection.io:latest && docker pull browserless/chrome:latest
docker run -d \
--name browserless \
--restart unless-stopped \
--shm-size="2g" \
-p 5556:3000 \
-e "DEFAULT_LAUNCH_ARGS=[\"--window-size=1920,1080\"]" \

I already had "Wait seconds before extracting text" to 10 seconds since i first installed changedetection 3-4 months ago
I ran the scans multiple times manually, only after that clear it actually worked. I don't know what's behind the scene, i can only say what i did and if it's working or not |

I have the same issue and it only happens when I want to run some browser actions. On a simple page load using Browserless everything works fine. It looks like the job times out and then the browser shuts down, hence ChangeDetection can't forward further commands to it. I tried setting the "Wait seconds before extracting text" param to 5, 10 and 15, but the issue still persists.

Is this delaying how fast we are monitoring site ? I haven't time to check site to 20 seconds for something's. Im wondering if that might be causing my issues cause no delays through the changedetection really do much. |

From my experience, that happens when the memory or CPU is low for the browserless container. Like when a Windows qemu VM (12g memory assigned. Hypervisor's memory is 32g but already the other linux vm with 18gb is running) is running but the shared memory for the browserless container is 2g at the same time. |

I believe pc is a little slower so maybe issue there. However under fast http plain text seems to be the best solution for me. |

Describe the bug
'Target page, context or browser has been closed'.
Parsing everything using the latest version of playwright. Some of them parse properly, some throw an error after updating to the latest and the first 0.40 release of changedetection.
I'm using the latest version of browserless, if that can help (not the one that is specified in the manual. just to test things.)
Version
0.40.0.2
To Reproduce
Update to the latest version of playwright & changedetection
