In this guide, we’ll walk through a scenario where a user encounters difficulties when trying to access and print fetched data. We’ll explore both the problem and the solution to help you get your web applications running smoothly.

Understanding the Problem

[[See Video to Reveal this Text or Code Snippet]]

This error indicates that the code is attempting to access a property from an object that does not exist yet. When fetching JSON data, there can be instances where the expected structure may not align with what is being accessed in the code.

The Solution

To resolve this issue, we need to ensure that we are correctly manipulating the fetched data and that the code is handling the potential asynchronous nature of the data fetch. Here’s a step-by-step solution:

Step 1: Update your HTML Structure

Step 2: Breaking Down the Code

Using x-data:

We define an object that includes orders, isLoading, and the orderSearch function.

The orders variable will be where we store the fetched data.

Fetching Data:

Using Conditional Logic:

In the <p> tag, we use x-text to conditionally display the inv_id of the first order when it exists. Otherwise, it will show "Loading..." until the data is completely fetched.

Step 3: Testing Your Code

After updating your code, it is crucial to perform a test:

Test the search functionality by inputting various order IDs, noting how the front-end handles the responses.
