PrimeNG ConfirmationService и ошибка MessageService

Question

Ошибка: node_modules / primeng / api / messageservice.d.ts:3:22 - ошибка NG6002: появляется в NgModule.imports AppModule, но не может быть преобразована в класс NgModule.

      This likely means that the library (primeng/api) which declares MessageService 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 Check if a newer version of the library is available, and update if so.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.

3 export declare class MessageService {
                       ~~~~~~~~~~~~~~
