SharePoint Event Handler access Personal Site

[WEISH1195]

Hi there,

my logic is when we auto-create a personal site and add a record into backend custom list. meantime the event handler will be triggered to config audit log and site policy in each personal site.

but sometimes I ran into a problem is like the following situation. does anyone have any idea on it??

Thanks
