Sorry you seem to be trying to mix Karate chrome and expect it to use a chromedriver. This is not supported. The executable should be the chrome executable itself or the default (recommended).
Also read the docs. If using chrome you can add userDataDir: null to the config so it will be not used on the command-line.
