Problem with moving dots movies on online experiments

URL of experiment: https://pavlovia.org/run/maha10/motiondisc/html/

Description of the problem: For some reason there seems to be several issues in running movies of moving dots. Either it simply doesn’t load and run or there is a problem which I can’t pin point to. Any help would be of help. Given that RDK is not supported online the only alternate is through movies but if movies can’t load or can’t play at the right speed then there is a problem for this type of experiment. Any help would be really appreciated.

With that link the experiment runs until it gets to the first trial where I get the error

TypeError: Cannot assign to read only property ‘undefined’ of object ‘#’

which refers to the line: psychoJS.importAttributes(trials.getCurrentTrial());

As per my crib sheet, you may have blank columns in one of your conditions files [dvbridges] e.g., Unknown resource, conditions file

So, please could you upload your conditions file here?
