Native HTTP plugin error

Ionic Native
5

For Any one who is still searching for solution…

My Old code was (using HttpClient by angular)

let contentHeaders = new Headers();
contentHeaders.set('Accept', 'application/json');
contentHeaders.set('Content-Type', 'application/json');
let qp = new URLSearchParams();
qp.set('action', 'countries');
this.http.get(API_DOMAINNAME+'api1/mssql.php',{ search:qp, headers: contentHeaders})

My New Code (using HTTP from @ionic-native/http)

let contentHeaders ={
'Accept': 'application/json',
'Content-Type':'application/json'
};
let qp = {action:'countries'};
this.http.get(API_DOMAINNAME+'api1/mssql.php', qp,contentHeaders)
