Most people try to use AI for Handling Async Errors Properly with a single vague prompt and get generic results. This guide takes a different approach: 4 targeted stages, from Diagnose the Wall through Prevent Recurrence, each with a prompt that gives the AI exactly the context it needs. Lovable's async functions often fail to catch or handle errors, leading to silent failures and unpredictable app behavior. This can cause data loss or incorrect app states, frustrating users and developers alike. These prompts help developers ensure robust error handling in async functions, preventing these issues. Works with ChatGPT, Claude, and Gemini.

Refactor Error Messages

Refactor the error messages in the function [FUNCTION NAME] to enhance clarity and provide actionable guidance. For each error message, provide a before and after example that illustrates the changes made. Ensure the new messages clearly convey the issue and suggest steps the user can take to resolve it. Aim for a tone that is helpful and informative, and include any relevant context that may assist users in understanding the errors.

Isolate and Fix

Test Error Handling

Create comprehensive test cases for the function [FUNCTION NAME] to ensure that all potential errors are caught and handled appropriately. Include scenarios for both synchronous and asynchronous errors, detailing the expected outcomes for each case. After running the tests, provide a summary of the results, highlighting any errors that were not handled as expected and suggesting possible improvements to the error handling logic. Format the results in a clear and organized manner for easy review.

Isolate and Fix

Verify the Resolution

Ensure the fixes have resolved the error handling issues.

Run Error Handling Tests

Please run all test cases related to asynchronous error handling in the application. Verify that each test case executes successfully and confirm that there are no unhandled errors present in the system. Provide a detailed report outlining any errors that were encountered, along with their specific locations in the code. Additionally, include recommendations for improving error handling based on the test results.

Verify the Resolution

Check Error Logs

Please review the error logs generated after running the application. Ensure that all logged errors adhere to the new format specified in the documentation. Provide a summary of any discrepancies found, including the number of errors that do not match the format and specific examples of those errors. Additionally, suggest any necessary steps to correct these issues and ensure compliance with the new logging standards.

Verify the Resolution

Validate Error Messages

Simulate various error scenarios in the application, including network failures, invalid inputs, and unexpected exceptions. For each simulated error, check if the new error messages are displayed as expected. Evaluate the clarity and helpfulness of these messages, ensuring they provide users with actionable information on how to resolve the issues. Document your findings in a structured format, highlighting any errors that do not meet clarity standards and suggesting improvements where necessary.

Verify the Resolution

Confirm Error Propagation

Please trace the error handling process in the application to confirm that errors propagate correctly to the top-level error handler. Start by identifying the different layers of the application where errors can occur, and describe how each layer handles errors before passing them up the chain.
