Style Library has permission issues SharePoint Online

[Ali Murtaza]

Dear All,

I am site administrator but when I am uploading or creating something under style library, it is giving error permission denied. The permission on library is inherited from site while I am also in owner group. What can be the reason?

@Ali Murtaza the issue is due to no script.
