Hello @Lee_F ,
thanks for reporting this issue. I was able to reproduce it and created a ticket (internal number AP-23905). The fix will most likely not make it into the 5.4.1 release which will be released soon. But it will be fixed with 5.4.2 at the latest.
The latest KNIME Analytics Platform version that does work is 4.6 if you want to update to a more recent version. The problem seems to be caused by a Google library update that we did with 4.7 but we still need to investigate in more detail.
Bye
Tobias
