Typescript Error Expected 0 arguments, but got 2 in Ionic Framework
The problem is with the loginAPI function definition.Adding the return type to Observable<any> made the compiler happy and solved the issue.
// auth-provider.tspublic loginAPI(credentials: {email:string,password:string}):Observable<any> { return this.http.post(this.apiUrl,data);}Still I don't really understand very well why, but at least now it compiles without any error.
In order to handler this you can create a class as follows,
public class credentials export { email : string; password: string;}and then,
public loginAPI(inCredentials : credentials ) { return this.http.post(this.apiUrl,data);}
