Hi Jeremy,
I was having the same problems as above where I was getting the following error: Access to XMLHttpRequest at ‘https://hjpatt-136.umd.edu/Web_Experiments/Slevc/spr/sprAudio.zip from origin ‘https://farm.pcibex.net’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.
I changed https://hjpatt-136.umd.edu/Web_Experiments/Slevc/spr/sprAudio.zip to https://www.hjpatt-136.umd.edu/Web_Experiments/Slevc/spr/sprAudio.zip 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 http://www.hjpatt-136.umd.edu/Web_Experiments/Slevc/spr/sprAudio.zip:1 Failed to load resource: net::ERR_CONNECTION_TIMED_OUT
Below is the section of code where I load my zip:
PennController.PreloadZip("https://www.hjpatt-136.umd.edu/Web_Experiments/Slevc/spr/sprAudio.zip");
PennController.CheckPreloaded();
Let me know if you have any ideas or need more information… Thanks for your help!
