Android ResourceNotFoundException in preview custom View

I've got a custom view, let's call it CustomView. In the initialization, I call the following method
textPaint.setTypeface(ResourcesCompat.getFont(getContext(),R.font.pretty_font));
In the app, this view works perfectly and the font is displayed as it should but the problem is that the preview of the view wont load in the editor with the following details:
android.content.res.Resources$NotFoundException: Font resource ID
0x7f090000 could not be retrieved.

Why won't this resource be loaded in the editor but it has no problem running in the app?
FYI, MinSdk = 21 and TargetSdk = 28

Don't call setTypeface in design mode. Use:
if (!isInEditMode()) {
textPaint.setTypeface(ResourcesCompat.getFont(getContext(),R.font.pretty_font))
}

I 'm trying to use more the 'android.material.xxx' than support.design.widget.
I also tried the support.design version but it doesn't seems to work :/
What might be the problem here ?

It could be the version of appcompat you using in your build gradle, I had the same problem using
implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'
so I just used
implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
