constructor(private dataservice : DataService){

     this.dataservice.fetchDataThroughPromise().subscribe(()=>{
      console.log('s')
    })
  }

service code

 fetchDataThroughPromise(){
    return this.http.get('https://restcountries.eu/rest/v2/all',
      {
        headers :new HttpHeaders({
          'content-type': 'application/json'

Just remove:

    headers :new HttpHeaders({
      'content-type': 'application/json'
    })

Final code:

fetchDataThroughPromise() {
  return this.http.get('https://restcountries.eu/rest/v2/all')
}
