instanciating WhatsApp() fails

[leggewie]

I got alright to work at least twice, but oftentimes it fails again the next day or after recreating the venv. I'm having trouble to troubleshoot and pinpoint the exact problem, to be honest. So, I will give as much information in order to find out what is going wrong.

My system runs Ubuntu Jammy. I created a venv with "python -m venv alright" and activate as "source alright/bin/activate", then "pip3 install alright". Sometimes it works and then sometimes it breaks for no immediately obvious reason.

I hope for some guidance to be able to look into and understand what is going wrong. The "DevToolsActivePort file doesn't exist"-error from selenium is very generic.

Selenium in general works, though. The following code exits with 0 and a
browser window pops up briefly.

Same here and this error log:
[4924:7236:0117/154006.283:ERROR:interface_endpoint_client.cc(695)] Message 1 rejected by interface blink.mojom.WidgetHost

@rafamelo01 How did you get that particular error, where is the error log located?

Could this be a regression in the latest chromium?

Edit: FWIW, hardcoding line 38 of init.py as ChromeDriverManager(version="108.0.5359.71").install(), does not change the situation for me, so most likely not a regression.

note to self: One thing you should not do is to call alright from within a directory containing alright source code, specifically one containing alright/init.py

@Kalebu Are you aware of a special meaning of a directory called User_Data for selenium? I am getting more and more certain that this problem has a lot to do with #104 FWIW, #107 breaks a currently working setup. I just don't see why.
