Can not upload SharePoint App to SharePoint App Catalog – when I was trying to upload the SharePoint app to the App Catalog site which I have downloaded from GitHub, I was not able to upload it – was getting the “The documents cannot be uploaded because different permissions are needed. Request the necessary permissions.”

The below error I got from the internet explorer browser:

Upload SharePoint App in App Catalog is failed
Upload SharePoint App in App Catalog is failed

Then I tried with Mozilla Firefox browser – drag and drop.

Then I got the below error:

“The documents cannot be uploaded because different permissions are needed. Request the necessary permissions.”

The documents cannot be uploaded because different permissions are needed. Request the necessary permissions.
The documents cannot be uploaded because different permissions are needed. Request the necessary permissions.

When I have googled around – people have suggested enabling the custom script. However, when I verified – it was already enabled.

By the way, I am a “Global administrator” in my tenant, so it is a bit frustrating to see permission or any sort of file uploading issues.

Solution:

After some research found that it is the permission issue in the app catalog site.

Go to the classic site collection administrator page from the SharePoint admin center, using the below shortcut URL:

Syntax:
https://yourtenant-admin.sharepoint.com/_layouts/15/online/SiteCollections.aspx
Example:
https://globalsharepoint2020-admin.sharepoint.com/_layouts/15/online/SiteCollections.aspx

Select your, app catalog site collection, click on the “Owners” dropdown list then click on the “Manage Administrator” link.

In the “manage administrator” dialog box – add the user who is facing the issue to upload the file in the “Site Collection Administrator” section.

Click on the OK button.

We need to wait for a couple of minutes until the loader disappears.
