[馃悰 Bug]: ConnectionFailedException: JdkWebSocket initial request execution error 路 Issue #2850 路 SeleniumHQ/docker-selenium (original) (raw)
What happened?
An attempt to upgrade Selenium hub and Chrome nodes from version 4.25.0-20240922 to the latest ones shows that there is an error related to CDP - ConnectionFailedException: JdkWebSocket initial request execution error.
The issue is reproducible starting from 4.26.0-20241101 till the latest versions: 4.33.0-20250525.
The only one workaround to avoid the issue - set Selenium flag --enable-cdp false for Chrome nodes and disable all tests that use CDP features.
