Could not initialize Chrome driver. Timed out waiting for driver server to start.

KNIME Analytics Platform
1

I’m trying to execute one of the simple examples of data visualisation in KNIME (02_JavaScript - 02_Example_for_JS_Line_Plot_Basic). However, I get an error related to the driver that displays the plot. I attach the complete log in this post. KNIME is configured to use the Bundled Chromium Browser. I have also tried to display it in my Chrome browser but it doesn’t work.

ERROR Line Plot (JavaScript) 0:150      Could not initialize Chrome driver. Timed out waiting for driver server to start.

The browser can be configured in Preferences -> KNIME -> JavaScript Views

Hi,

can you provide some more information on the environment you’re trying to run this in? Which OS are you using and which version of KNIME? That might help us narrow down what the problem is.

Looking closer at the stack trace it seems that the chromedriver executable can not start (not the Chromium itself but another intermediate program). It is very likely blocked by a firewall or virus program running on your system. Can you verify that?
