An unhandled exception occurred: context.getProjectMetadata is not a function

I get this error message, when I try to run my ionic app in the simulator.

`An unhandled exception occurred: context.getProjectMetadata is not a function`

The command I'm using to run my project (works fine on angular 8, and angular toolkit 2.1)

`ionic cordova run ios --livereload --target '...'`
