What am I doing wrong with this Angular "get" example?

I'm going through the W3 course on Angular and I'm working through this example: https://www.w3schools.com/angular/tryit.asp?filename=try_ng_customers_mysql

Here's my "term_list_json.php" code:

<?php

header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=UTF-8");

require_once("term_class_pdo.php");

$current_discipline="";
$new_list= new TermAdmin;
$term_display=$new_list->term_list();

$output="";

foreach($term_display as $term)
{
	if($output !="") 
	{
		{$output.= ", ";}
	}
	$output.= '{"disicpline": "' . stripslashes($term['discipline']) .'", ';
	$output.= '"term": "' .stripslashes($term['term']) .'", ';
	$output.='"definition"; "'. stripslashes($term['definition']).'"}';
}
$output = '{"records": ['.$output.']}';

echo $output;

?>

You can see it live at http://brucegust.com/adm/term_list_json.php

Now, here's my code on the Angular side:

<!DOCTYPE html>
<html lang="en">

<title>Angular Tutorial</title>
<link href="css/stylesheet.css" rel="stylesheet" type="text/css" />
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<style>

  border: 1px solid grey;
  border-collapse: collapse;
  padding: 5px;
}
table tr:nth-child(odd) {
  background-color: #f1f1f1;
}
table tr:nth-child(even) {
  background-color: #ffffff;
}
</style>
</head>
<body style="white-space: normal;">

<div ng-app="myApp" ng-controller="myCtrl">

<table>
	<tr ng-repeat="x in terms">
		<td>{{x.discipline}}</td>
		<td>{{x.term}}</td>
	</tr>
</table>

</div>

<script>
var app=angular.module("myApp", []);
app.controller('myCtrl', function($scope, $http) {
	$http.get("http://brucegust.com/adm/term_list_json.php")
	.then(function (response) {$scope.terms = response.data.records});
});
</script>

<p>With the "ng-options" directive, the selected value can be an object...</p>

</body>
</html>

When you run the page at http://brucegust.com/adm/angular/json_retrieval.php, you get a blank screen, save some text. But there's a huge error that I've got pictured below.

Now sure what I'm doing wrong or how to process that error.

What do I need to change?

Thanks!

That error is indicating that there is a problem with the call, and you are not handling the error.  Alter your code to the following:
var app=angular.module("myApp", []);
app.controller('myCtrl', function($scope, $http) {
	$http.get("http://brucegust.com/adm/term_list_json.php")
	.then(function (response) { $scope.terms = response.data.records; })
	.catch(function (error) { console.error(error); });
});

Open in new window

This will show the actual error in the console.  Once you have modified your code, if you are unable to troubleshoot the problem, check back here.

Hey, Jim!

I did your suggestion and this is what I had in my console (I apologize for the volume, but I wanted you to see what was there...)
