[hexedit]

Angular version: 9.1.1 ngx-jsonapi version: 2.1.15 Compilation result: ERROR in node_modules/ngx-jsonapi/ngx-jsonapi.module.d.ts:6:44 - error NG6005: NgxJsonapiModule.forRoot returns a ModuleWithProviders type without a generic type argument. Please add a generic type argument to the ModuleWithProviders type. If this occurrence is in library code you don't control, please contact the library authors. Explanation: Module import in Angular 9 should return ModuleWithProviders<NgxJsonapiModule>
