Hi I have a problem with graphical or image outputs like roc curve.

also the error text;

I have a similar problem on a McOS machine since upgrading to Chrome 72. I have tried the various browser settings but they do not seem to work anymore.

Edit: restarting KNIME and switching to the version 70 settings seem to help, but there still could be a problem …

Hi,

there seems to be an incompatibility introduced with Chrome 72, so that it will not work anymore with the ChromeDriver that is shipped with KNIME 3.7. Is there a reason you are not using the Bundled Chromium for both image generation and view display? That should work out of the box and does not rely on the Chrome browser installed on your system.
