Dear essentialobjects team,

we upgraded EO.WebBrowser and EO.WebBrowser.WPF from 23.4.26 to 2024.0.20.

With the new version the same code as previous crashes.
After downgrading it works again.

Calling preload raises this exception:

Hi,

We tested Preload method here and it works fine. Please collect the runtime logs (the same log you posted in the other thread) and send it to us. See here for more details:

https://www.essentialobjects.com/doc/common/collect_logs.html

Once we have the log we will look into it and see what we can find. We may need a repro project from you if we can not find anything from the logs.

Thanks!

Hi,

thanks for your fast response.

We fixed the issue. It was a misstake on our side.

We pass "ExtraCommandLineArgs" to the engine to modify the --user-data-dir.
The custom user-data-dir value was a invalid path. It seems the new version does not handle invalid paths as the user-data-dir value and throws a exception.
We fixed the user-data-dir value and now the preload works fine.

Thank you for your support and have a nice day.
You can close this thread.
