    This likely means that the library (ng2-datepicker) which declares NgDatepickerModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

So is there any plan at least? this project is not updated over two years. many issues and many pending pull-request. I can fix this but why should I wait for this fix to get applied? Since this is breaking my whole pipe line. I prefer to use other alternatives. lets never fix this.
