Minimal Reproduction

I have more themes in the application and I call "@include datePickerTheming.mat-datepicker-theme($theme)" for every theme the same way like for other components. This datepicker gives me the error during ng serve.

Expected behavior

No build warnings.

I used
@include datePickerTheming.mat-datepicker-color($theme);
instead of
@include datePickerTheming.mat-datepicker-theme($theme)
and that fixed the issues.
