Module loader crashes when trying to upload an MLP

Hi all

We created our own MLP for Sugar. This was working fine some time ago (I checked last month). We created a new version of our software along with some tweaks for the MLP and when we do, we recommend our customers to update their MLP.

Now, we got multiple support tickets of upset customers, mentioning that they are unable to upload our MLP. When trying meself, I have the same thing happening. Upon uploading, we get a blank screen.

The only thing I can share is an error in the devtools:

Access to XMLHttpRequest at 'appcatalog-eu-central-1.service.sugarcrm.com/catalog from origin '...' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Some feedback here would be highly appreciated Slight smile.

Kind regards

Jan
