[🐛 Bug]: Randomly get org.openqa.selenium.WebDriverException: Unable to parse:

What happened?

I was trying to find a way to reproduce the org.openqa.selenium.TimeoutException: java.net.http.HttpTimeoutException from https://github.com/SeleniumHQ/selenium/issues/9528#issuecomment-1282632363 but I face randomly another exception : org.openqa.selenium.WebDriverException: Unable to parse:

I don’t know why I have this exception because the test can run with success more than 500 times.

How can we reproduce the issue?

I didn’t have much hope when I opened this issue but now Selenium 4 is stable. No “Unable to parse” or “Failed to decode request as JSON”. Thanks a lot @joerg1985 !

@JulienBreton Could you set <trimStackTrace>false</trimStackTrace> in the <configuration> of the maven-surefire-plugin. This should lead to a longer stack trace after the test failed, see: https://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html#trimStackTrace
