Loader Dismisses Before Rules Are Fetched Preventing Incorrect Routing Information Display

Introduction

This article addresses a critical issue encountered in version v1.9.0 of the application within the UAT environment, specifically related to order routing. The problem arises when the network connection is throttled to a slower speed, causing the loader to dismiss prematurely before the routing rules are fully fetched. This premature dismissal leads to the display of incorrect routing run information, which can be confusing and misleading for users. Understanding the intricacies of this issue and its impact on user experience is crucial for developers and stakeholders alike. This article will delve into the current behavior, the expected behavior, the steps to reproduce the issue, and provide additional context to facilitate a comprehensive understanding and resolution of the problem. Addressing this issue is paramount to ensuring the reliability and accuracy of the order routing information presented to users, ultimately enhancing their experience with the application. Proper handling of asynchronous operations and user interface feedback is essential in modern applications, and this case highlights the importance of these aspects.

Current Behavior

The current behavior exhibits a significant flaw in the application's handling of asynchronous data fetching. When a user accesses the application under normal network conditions, the routing rules are fetched and displayed without issue. However, when the network speed is throttled to simulate slower connections, a critical problem emerges. The loader, which is intended to provide visual feedback to the user that data is being loaded, dismisses prematurely. This dismissal occurs before the routing rules have been completely fetched from the server. Consequently, the application displays incomplete or incorrect routing run information. This discrepancy between the actual state of the routing rules and the displayed information can lead to user confusion and potential errors in decision-making. The user might make incorrect assumptions about the routing process, leading to operational inefficiencies or even incorrect order processing. The root cause of this behavior lies in the application's logic for managing the loader and the asynchronous fetching of routing rules. There appears to be a lack of synchronization or proper handling of the asynchronous operation, causing the loader to dismiss based on a premature condition rather than the actual completion of the data fetching process. Addressing this issue requires a thorough examination of the application's codebase to identify and rectify the flawed logic. Effective error handling and user feedback mechanisms are crucial in these scenarios to maintain a positive user experience. This premature dismissal of the loader not only affects the visual feedback but also undermines the reliability of the displayed information, making it imperative to resolve this issue promptly.

Expected Behavior

The expected behavior of the application is to provide clear and accurate feedback to the user regarding the status of data fetching operations, particularly for critical processes such as order routing. In this specific scenario, the user should receive a clear indication that the routing rules are still being fetched, especially when the network connection is slow. This can be achieved by ensuring that the loader remains visible until all routing rules have been successfully retrieved from the server. The loader should act as a reliable indicator of the data loading process, preventing the display of incomplete or incorrect information. By maintaining the loader's visibility until the data is fully fetched, the application can avoid misleading the user and ensure that they have a complete and accurate view of the routing rules. This approach aligns with best practices in user interface design, where feedback mechanisms are used to keep the user informed about ongoing processes. Furthermore, the expected behavior includes robust error handling to address potential issues during data fetching, such as network timeouts or server errors. If an error occurs, the application should display an appropriate message to the user, guiding them on how to proceed. This proactive approach to error handling can significantly improve the user experience and prevent frustration. User-centric design principles emphasize the importance of providing clear and timely feedback, and the expected behavior described here reflects these principles. Ensuring that the user is aware of the data fetching status is crucial for maintaining trust and confidence in the application.

Steps to Reproduce the Issue

To reproduce the issue and observe the incorrect routing information display, follow these steps carefully. These steps are designed to simulate the conditions under which the problem occurs, specifically a slow network connection. This systematic approach allows developers and testers to consistently replicate the issue and verify any proposed solutions.

Login to the app using valid credentials: Begin by logging into the application with a valid user account. This ensures that you have the necessary permissions to access the order routing functionality.
Throttle the network to a slower speed: This is a crucial step in replicating the issue. Use a network throttling tool or browser developer tools to simulate a slow network connection. Setting the network speed to a lower bandwidth will mimic the conditions under which the loader dismisses prematurely. A common throttling speed to use for testing is a 'Slow 3G' or similar profile, which represents a significantly slower connection than typical broadband speeds.
Open a brokering run to view its rules: Navigate to the order routing section of the application and open a brokering run to view its associated rules. This is the area where the incorrect routing information is displayed when the issue occurs.
Observe the issue: Pay close attention to the behavior of the loader and the displayed routing information. You should observe that the loader dismisses before all the routing rules are fetched, resulting in the display of incomplete or incorrect information. This confirms the presence of the issue. By following these steps, you can reliably reproduce the issue and gather evidence for debugging and resolution. Consistent reproduction steps are essential for effective problem-solving and validation of fixes.

Environment Details

The environment details are crucial for understanding the context in which the issue occurs. The specific version of the application and the environment in which it is running can significantly impact the behavior of the software. Knowing these details helps developers and testers focus their efforts on the relevant codebase and configurations. In this case, the issue has been identified in:

Version: v1.9.0
Environment: UAT (User Acceptance Testing)

This information indicates that the problem exists in the v1.9.0 release of the application and has been observed in the UAT environment. The UAT environment is typically used for final testing and validation before a release is deployed to production. Therefore, identifying and resolving the issue in this environment is critical to preventing it from affecting end-users. The version number provides a specific reference point for developers to locate the relevant code and configurations. It also helps in tracking the issue across different releases and ensuring that the fix is included in future versions. The environment designation, UAT, highlights the importance of addressing the issue promptly to maintain the quality and stability of the application before it is released to production. Precise environment details are essential for effective bug tracking and resolution, enabling targeted debugging and testing efforts.

Additional Information

Additional information can provide valuable context and insights into the issue, aiding in its understanding and resolution. In this case, a Jam.dev link (https://jam.dev/c/3c7e6d88-6eb6-448b-8b34-831b3877c5f9) has been provided, which likely contains a recording or detailed description of the issue in action. This type of information is extremely helpful for developers as it allows them to see the problem firsthand and gain a better understanding of the user experience. The Jam.dev link might include screen recordings, console logs, network requests, and other relevant data that can assist in diagnosing the root cause of the problem. By examining this additional information, developers can identify patterns, pinpoint error messages, and trace the sequence of events leading to the issue.
