QML debugging issue with Boot to Qt on macOS

Steps to reproduce:

• Install docker desktop and run it before launching installer
• Install Boot to Qt toolchain (6.8.0 used) and QtCreator 14.02 or 15.0.0 beta1 to macOS
• do the usual device setup stuff and enable debugging/profiling from QtC Projects -> Build Settings
• open a QML application and set a  QML break point
• start debugging
• "Step over" twice

Expected result:

Debugger stops to break point and no errors shown.

Actual result:

Debugger stops at break point but Application Output shows:

Do you need "set solib-search-path" or "set sysroot"?QML debugging is enabled. Only use this in a safe environment.
