How to tell htmlunit to ignore certain errors

java htmlunit

I am currently trying out HtmlUnit. I want to fill out an form and then submit it. But this results in an error, which seems to be caused by a file not being accessible, which results in a connection reset being thrown. How can I suppress this, as this is not crucial considering the loading process of the whole website? It doesn't seem to affect the program, though, I just want it to be silenced.

Try the following

webClient.setThrowExceptionOnFailingStatusCode(false);

It should handle the 404 (Not found) error status.
