PennController for IBEX Forums Support .zip file problems Reply To: .zip file problems


Hi Jeremy,

I was having the same problems as above where I was getting the following error: Access to XMLHttpRequest at ‘ from origin ‘’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

I changed to and that solved the above error, but I still cannot access my zipped resources.

It seems like preloading my zip file goes fine, however, when I “check preloaded” I do not actually see anything in my debugger log to indicate the filed were loaded. Then, when it reaches the point in my experiment when I actually try to access the resources, I see the “Please wait, resources are loading…” message before the experiment crashes altogether with the following three errors:

1. PennController.js:65 Uncaught (in promise) DOMException: The element has no supported sources.
2. PennController.js:65 Uncaught Error: InvalidStateError: Failed to read the ‘responseText’ property from ‘XMLHttpRequest’: The value is only accessible if the object’s ‘responseType’ is ” or ‘text’ (was ‘arraybuffer’).
at XMLHttpRequest.n.onreadystatechange (PennController.js:65)
3. PennController.js:65 Failed to load resource: net::ERR_CONNECTION_TIMED_OUT

Below is the section of code where I load my zip:


Let me know if you have any ideas or need more information… Thanks for your help!
