Hi,

Is there anyone here who have experienced an issue related to Access to XMLHttpRequest where an origin has been blocked by CORS?

Please see attached image for further details: CORS Issue.JPG

Note that I am using a Sharepoint list for my backend which has more than 2k items. Not sure if this is related to the issue...

Any help will be much appreciated. Thanks!

Regards,

Did you get any info from Microsoft on this, also getting it now.
And it actually will affect the applications loading times.

@Graham, unfortunately, not. I actually just let this pass after talking to Microsoft Support.

But it doesn't cause any problems now on my app.. I hope same thing goes to you.

Did you manage to get this resolved? I am having the same issue when converting a portal from trial to production.

Hi,

I am unfortunately not too experienced with this error. It looks like some kind of policy thing but I am not certain. This might be a better questions for Microsoft Support to take a look at. I'll include a link below; if you would like to go down that route. Otherwise if any other communities members might know feel free to chime in.

If you would like to create a ticket with Microsoft Customer Support here is a link on how to do so: https://docs.microsoft.com/en-us/power-platform/admin/get-help-support

Regards,

Alex
