Transferhttp is not wokring about universal-starter

Do you use absolute URL for the request?
You need to reproduce the problem with the public repository.

Hi Gorvin,

Thank you for your reply and suggestion. But it doesn't work even after ensuring absolute path.

Please find code snippets :

component :

self.apiService.get('getPapersOfBoard', 'boardName=' + self.boards.toUpperCase()).subscribe(res => {
        self.apiService.list('getSubjectDescription').subscribe(result => {
          result['sujectDescription'].forEach(element => {
            res.boardName['class'].forEach(cl => {
              cl['subject'].forEach(sub => {
                if (sub.name === element.subject_id.name && cl.name === element.class_id.name
                  && self.boards.toUpperCase() === element.board_id.name) {
                  sub.description = element.description;
                  sub.title = element.title;
                }
              });
            });
          });
          self.apiService.setData(res.boardName);
          self.getTree(params);
          self.spinner.hide();
        });
      });

Apiservice.ts

constructor(private httptransfer: TransferHttpService, @Inject('ORIGIN_URL') public baseUrl: string,) { }
.....

 get(modelName: string, id: string): Observable<any> {
    return this.httptransfer.get(environment.apiEndpoint.concat(modelName).concat('?').concat(id));
  }

  list(modelName: string, criteria = {}, limit = '1000', skip = '0', sort = 'updatedAt DESC'): Observable<any> {
    const listOptions = new HttpHeaders();
    return this.httptransfer.get(environment.apiEndpoint.concat(modelName));
  }

environment.ts

export const environment = {
  production: false,
  apiEndpoint: 'http://0.0.0.0:3000/api/',
  isServer: true,
  // for prerender
  host: 'http://localhost:4200/',
};

Can you please help me out with this?

Dependency injection issue solved.

@shahbazkhan054 can you write more information about the solution?

Changes I made to fix the issue :

1. The TransferHttpModule and transferHttpService should be used in one module.
   I removed TransferHttpModule from shared module to AppModule and also add provider as transferHttpService and apiService.
2. Typescript version : 3.1.1 -> 3.1.6
