Hi @Qingbo Meng ,

As the message, you should check the permission of your app. Your app might only have permission to one of the site. You should register a new app for the other site. Please refer to following document

https://learn.microsoft.com/en-us/sharepoint/dev/solution-guidance/security-apponly-azureacs

In your case, you could use the following xml

<AppPermissionRequests AllowAppOnlyPolicy="true"> <AppPermissionRequest Scope="http://sharepoint/content/sitecollection" Right="FullControl" /> </AppPermissionRequests>
