Web Experiment in MacOS with Chrome and Safari

Description of the problem:
Same demo experiment runs in Safari and Firefox, but show error in Chrome.

It gives below error message.

Unfortunately we encountered the following error:

  • TypeError: Cannot read property ‘readPixels’ of undefined

Try to run the experiment again. If the error persists, contact the experiment designer.

It’s interesting, because in the previous post, Safari seems not worked properly.
