[SOLVED] Error after clicking "Launch"


When running an experiment and clicking “Launch”, the experiment often failed to launch. This happens with my experiment and also with a tutorial experiment - see attached screenshots.
What should I do?

Thank you in advance,



Hi Zdenek,

Your experiments seem to have been created very long ago, since they don’t have the “Cloned on…” date in the bottom right corner (see screenshot). That may be a reason why they don’t work anymore.
Can you try to clone, for example the “Tutorial Baseball experiement - solution” from the templates again and try to launch? On my side it worked nicely.
