Error Details

Let's break down the specifics of the error. Understanding the error details is crucial for effective troubleshooting. This section covers the key information related to the 'Failed to fetch' error in IntuneAssistant, providing a clear picture of what's going wrong.

• Error Message: Failed to fetch
• Correlation ID: N/A
• Timestamp: 2025-11-14T10:03:10.521Z
• URL: https://test.intuneassistant.cloud/devices/overview/

The error message "Failed to fetch" is a generic error indicating that the application was unable to retrieve data from the specified URL. This could be due to a variety of reasons, such as network connectivity issues, server problems, or problems with the IntuneAssistant application itself. The absence of a Correlation ID makes it slightly more challenging to track down the exact cause of the error, as this ID would typically help in tracing the request through various services.

The timestamp provides the exact time when the error occurred, which can be useful for correlating the error with other events or logs. The URL indicates the specific endpoint that the application was trying to access when the error occurred. In this case, it's the /devices/overview/ endpoint, which suggests that the application was trying to retrieve a list of devices managed by Intune.

To further investigate this issue, you might want to check the following:

1. Network Connectivity: Ensure that the device running IntuneAssistant has a stable internet connection and can access the specified URL.
2. Server Status: Verify that the IntuneAssistant server is up and running and that there are no known outages or issues affecting its availability.
3. Application Logs: Check the IntuneAssistant application logs for any additional error messages or warnings that might provide more context about the cause of the "Failed to fetch" error.
4. Browser Console: If you're using IntuneAssistant in a web browser, open the browser's developer console and check for any JavaScript errors or network requests that might be failing.
5. Firewall Settings: Ensure that there are no firewall rules blocking access to the IntuneAssistant server or the specified URL.

Understanding these details is the first step towards resolving the error and getting IntuneAssistant back to working order. Keep digging, and don't hesitate to explore these areas for potential solutions.

Steps to Reproduce

To effectively address an issue, it's essential to understand how it occurs. This section details the exact steps needed to reproduce the 'Failed to fetch' error in IntuneAssistant. By following these steps, you can confirm the issue and test potential solutions.

1. Start IntuneAssistant.
2. Navigate to the devices overview section.
3. Observe that the application attempts to load devices.
4. Notice that the loading process stalls indefinitely.
5. Wait until the application times out.
6. Observe the error message: "No response received from API"

These steps clearly outline the process that leads to the error. The key point is that the application gets stuck while trying to load devices, eventually timing out and displaying the "No response received from API" message. This indicates a problem with the API call that IntuneAssistant is making to retrieve device information.

Here are some additional considerations when trying to reproduce the error:

• Network Conditions: Try reproducing the error under different network conditions. For example, try using a different Wi-Fi network or a wired connection. This can help determine if the issue is related to network connectivity.
• Application Version: Make sure you're using the latest version of IntuneAssistant. Older versions may have bugs that have been fixed in newer releases.
• Device Configuration: Try reproducing the error on different devices. This can help determine if the issue is specific to a particular device or configuration.
• Tenant Size: If you have a very large Intune tenant with many devices, the API call may take longer to complete. Try increasing the timeout value to see if that resolves the issue.
• API Throttling: Intune APIs are subject to throttling limits. If you're making too many API requests in a short period of time, you may encounter errors. Try reducing the frequency of your requests or implementing a retry mechanism.

By carefully following these steps and considering these additional factors, you should be able to reliably reproduce the error and test potential solutions.

Expected Behavior

Knowing what should happen is just as important as knowing what does happen. This section outlines the expected behavior of IntuneAssistant when loading devices. Understanding the desired outcome helps to clearly define the problem and evaluate potential solutions.

The expected behavior when loading devices in IntuneAssistant is that the application should successfully retrieve and display a list of all devices in the tenant. This includes:

• Successful API Call: The application should be able to make a successful API call to the Intune service to retrieve device information.
• Data Retrieval: The API should return a complete list of devices, including their properties and status.
• Timely Loading: The application should load the device list in a reasonable amount of time, without timing out or freezing.
• Accurate Display: The application should display the device list accurately, with all device information clearly visible.
• No Errors: The application should not display any error messages or warnings during the loading process.

In other words, when you navigate to the devices overview section in IntuneAssistant, you should expect to see a comprehensive and up-to-date list of all devices managed by your Intune tenant, without any errors or delays.

If the application fails to load the device list, displays an error message, or takes an excessively long time to load, then it is not behaving as expected. This indicates that there is a problem with the application, the API, or the network connection.

Understanding the expected behavior is crucial for identifying and resolving issues with IntuneAssistant. By comparing the actual behavior to the expected behavior, you can quickly pinpoint the source of the problem and take corrective action. If the actual behavior deviates from the expected behavior, then further investigation is warranted to determine the root cause of the issue.

Potential Solutions and Workarounds

Now that we understand the error, how to reproduce it, and the expected behavior, let's explore some potential solutions and workarounds to resolve the issue. These suggestions are based on common causes of the 'Failed to fetch' error and should provide a starting point for troubleshooting.
