[Selenium] Start WebDriver errors out with "Unable to load class"

mwiegand · February 9, 2025, 4:17pm

since the latest update the Start WebDriver errors out and I cannot figure out why. Any idea?

Console
2025-02-09 17:12:25,633 ERROR Start WebDriver 3:1126:0:1666 Execute failed: Could not initialize class org.openqa.selenium.remote.http.ClientConfig

Here is the knime.log

Hi Mike,

what did you update:

KNIME
Selenium Nodes
Both

Have you tried: Selenium Nodes — Frequently asked questions

The last update was rather comprehensive but I roughly recall that I’ve seen Selenium amongst all others too.

Placing a new WebDriver Factory and testing the settings triggers the issue:

To test things out, I pointed the binaries to my Chrome installation and started with --clean. Chrome started but this error was thrown (I cannot copy the message).

Reverting the setting and trying again did not threw the error and Chrome got started properly.

Restarting again w/o the clean flag resolved the issue. Thanks for your guidance

Cheers
Mike
