Opening Admin Plugins results in Error

1. nopCommerce version 4.1 (No Source Version)
2. A list of available plugins
3. Erorr message
4. Login in admin Configuration > Plugins (site_url/Admin/Plugin/List)
5. No modifications. Just downloaded and installed.

I was getting this error message after deplying my own source code, but it resulted in the same error, but with a different path. The code is trying to access a path that is not available and is probably the location of source code on a dev machine.

here is the error stack pertaining to OfficialFeedManager.cs

System.OperationCanceledException: The operation was canceled.

Thanks! Already reported

Hello
Is there a solution to this problem?

Yes, it's fixed

my fault.
I haven't deleted a copy.

Hi,

I also had the same error with nopcommerce 4.1
When I built at localhost, there was no error, but restoring the database and files from localhost to the server encountered this error. The nopcommerce 4.1 version is the nosource version I downloaded on nopcommerce
