Online experiment issue: TypeError message

URL of experiment: https://pavlovia.org/run/vanlou22/wordjumbler/html/ Everything runs perfectly on my home computer but this error message comes up when the study is run online: Unfortunately we encountered an error: TypeError: Cannot assign to read only property ‘undefined’ of object '#' Try to run the experiment again. If the error persists, contact the experiment designer. Thank you for any help in advance!
