Joe Spinelli Lightning Web Component not showing API call results
Hello!
I'm working with a pretty basic Lightning Web Component. I've followed this guide loosely. https://trailhead.salesforce.com/en/content/learn/projects/lwc-build-flexible-apps/record-list
The only differentiation is that I'm using a different API.
Here is my js file
I can run it in anonymous window and see results. I also see the aura log that proves it is being called. It returns 10 records, but when I view the results the objects returned are just blank objects.
I'm not sure why it is showing up as blank. Am I being hit by some kind of limit when data is being sent to the front end?

Here is my js file
import { LightningElement, wire } from 'lwc';
import getStarships from '@salesforce/apex/StarshipController.getStarships';
export default class StarshipViewer extends LightningElement {
starships;
error;
connectedCallback(){
getStarships()
.then(result => {
this.starships = result;
})
.catch(error => {
this.error = error;
});
}
}
Here is my controller
public inherited sharing class StarshipController {
@AuraEnabled
public static List<Starship> getStarships(){
List<Starship> starships = new List<Starship>();
string strEndPointURL = 'https://swapi.dev/api/starships/';
starships = getStarships(strEndPointURL);
system.debug(starships.size());
return starships;
}
private static List<Starship> getStarships(string strEndPointURL){
String strResponse = null;
if(String.isNotBlank(strEndPointURL)) {
HttpRequest request = new HttpRequest();
request.setEndpoint(strEndPointURL);
request.setMethod('GET');
request.setHeader('Accept', 'application/json');
try {
Http http = new Http();
HttpResponse response = http.send(request);
if (response.getStatusCode() == 200 ) {
strResponse = response.getBody();
}
else {
throw new CalloutException(response.getBody());
}
}
catch(Exception ex) {
throw ex;
}
}
if(!String.isBlank(strResponse)) {
JSON2Apex res = JSON2Apex.parse(strResponse);
return res.results;
} else {
return new List<Starship>();
}
}
}
