Angular 8 + Spring Boot: required String parameter is not present

I get required String parameter is not present when I want to invoke my GET endpoint and I don't know what's wrong with my code:

Angular:

  getFrameworkPolls(year: string, companyId: string) {
    const params = new HttpParams();
    params.append('year', year);
    params.append('companyId', companyId);
    return this.http.get<IFrameworkPoll[]>(`${this.url}/poll`, {params});
  }

Spring:

@GetMapping("document/frameworks/poll")
public ResponseEntity<List<FrameworkPoll>> findFrameworksWithPolls(@RequestParam String year, @RequestParam String companyId) {
    return pollFacade.findFrameworksWithPolls(year, companyId);
}

ERROR:

HttpParams is intended to be immutable. The append method don't modify the existing instance. Instead they return new instances, with the changes applied, hence you need to assign as below:

getFrameworkPolls(year: string, companyId: string) {
    const params = new HttpParams();
    params = params.append('year', year);
    params = params.append('companyId', companyId);
    return this.http.get<IFrameworkPoll[]>(`${this.url}/poll`, {params});
  }
