This is a TypeScript issue, see:

• An accessor cannot be declared in an ambient context. #3513
• TS 3.7: --declaration output for getter only property now is a getter instead of readonly microsoft/TypeScript#33939

To solve this problem, update your TypeScript version to 3.7.4. I'll publish another patch release with a downgraded TS

Built a new Angular 9 project based on Angular-CLI release 9.0.0-rc.5 and @nestjs/ng-universal.
No errors on build. But after startup I got one exception.

@nestjs/ng-universal is not compatible with Angular 9. There is no official Angular 9 release yet.
