Getting Improving Async Error Handling right takes more than a single prompt. This 4-stage guide covers Diagnose the Wall, Isolate and Fix, Verify the Resolution, and more, breaking the whole process into focused steps where each prompt builds on the last. Async functions in Bolt may fail to catch, handle, or propagate errors correctly, leading to silent failures. If these issues remain unresolved, debugging becomes increasingly difficult, causing delays in development. By following this guide, developers can ensure robust error handling in their async functions, improving reliability and maintainability. Every prompt is optimized and runs in ChatGPT, Claude, and Gemini.

Provide a brief explanation of how the error handling improves the function's reliability.

Isolate and Fix

Rewrite Async Function with Error Propagation

Rewrite the async function located at [FILE]:[LINE] to explicitly propagate errors by using 'throw' within the catch block. Make sure to update the function signature to indicate that it now returns a promise that can reject with an error. Additionally, provide a brief explanation of how this change improves error handling in the function.

Isolate and Fix

Scoped Change for Error Handling

Revise the error handling mechanism in the async function located at [FILE]:[LINE]. Implement a centralized error handler that captures all errors generated within this function. Ensure that each error is passed to this handler to maintain consistent logging practices across the application. Provide a brief explanation of how this change improves error management and logging consistency.

Isolate and Fix

Format Enforcement for Async Functions

Please create a guideline document for enforcing a consistent error handling format for async functions in the project. Specify that all async functions must include try-catch blocks and detail how to return errors appropriately. Include examples of both correct and incorrect implementations, and outline the consequences of not following these guidelines.

Isolate and Fix

Correct Async Function Dependencies

Identify and correct any dependencies used in the async function located at [FILE]:[LINE]. Ensure that all necessary libraries for error handling are properly imported and utilized within the function. Provide a revised version of the async function that includes these corrections and explain how each change improves error handling.

Isolate and Fix

Verify the Resolution

Confirm that the async function now correctly handles and propagates errors. Check for any remaining silent failures.

Run Tests for Error Handling

Please run the test suite located at [FILE] on line [LINE] that includes the async function for error handling. Verify that all tests pass successfully and ensure that any errors are logged according to the expected behavior. After running the tests, provide a summary of the results, including any errors that were encountered and how they were logged.

Verify the Resolution

Show Diff of Async Function Changes

Please provide a detailed comparison of the async function located at [FILE]:[LINE] before and after the recent changes. Highlight the specific modifications made for error handling, including any new error handling mechanisms introduced and how they improve the function's robustness. Format the output to clearly indicate the differences, using annotations or comments to explain the significance of each change.

Verify the Resolution

Replay Failing Scenario

Replay the original scenario that caused the async function to fail. Verify that errors are now being caught and logged correctly by providing a detailed report. Include the steps taken to reproduce the issue, the expected behavior, and the actual outcome after the resolution. Format the report with sections for the scenario description, error logs, and any additional observations.

Verify the Resolution

Check Edge Cases for Error Handling

Identify and analyze the edge cases for the asynchronous function located at [FILE]:[LINE]. Please provide a detailed report that includes a list of all potential errors that could arise, how each error is currently handled, and any recommendations for improving error handling.
