Mojave - Not authorised to send Apple events to Mail

I’ve upgraded to Mojave and now get an error Not authorised to send Apple events to Mail. when I try to run:

**tell application “Mail” to set ListMessage to selection – take all emails selected

How do I fix this?

This error does not occur when I use Script Editor, only Script Debugger.

I have given Script Debugger Full Disk Access in the Security & Privacy section of Settings.

You need to give Script Debugger permission under Automation, not (or as well as) Full Disk Access.

This seems to have done the trick. Thanks!
