The data from Angular2 Observable Subscription appears undefined, although a closer look at the Browser Debug reveals otherwise

Is it possible there is an issue with the data subscription process? Upon subscribing to data from a service call, 'undefined' is returned as the data set.

Surprisingly, when I debug the code in the browser, it clearly shows that the correct data is being retrieved through the subscription. Below is an example of the code snippet. Any insights on what may be causing this discrepancy would be greatly appreciated.

this.userService.getUserTypes().subscribe(data => {
    console.log('data length is ' + data.result.length);
});

Answer №1

When utilizing a subscription, it's important to note that the data may not be immediately available. As a result, using .length may not always yield accurate results. Consider trying the following approach:

if (data) {
     console.log('The length of the data is ' + data.result.length);
}
