Identifying the Problem

The error you're facing often occurs when the function specification in your OpenAI API call lacks some required fields or when the format expected by the API isn’t strictly followed. In your case, you're trying to create a SQL query based on user questions regarding properties and finance, which is a clever approach. However, slight misconfigurations can lead to errors.

Common Reasons for InvalidRequestError

Incomplete Function Definitions: The OpenAI API expects certain fields within your function definitions to be present. Missing these can trigger errors.

Incorrect Parameter Structuring: The structure of the 'parameters' field must adhere to the schema expected by the API.

Invalid JSON Formatting: Ensure that the JSON data sent to the API is correctly formatted with all necessary keys.

Solution: Modifying Your Function Definitions

To resolve the issue, you should modify your function definitions by ensuring all required properties are set correctly in the parameters. Let’s take a closer look at how your function should be structured.

Revised Function Structure

Here’s how to structure your function definition properly:

Why This Structure Is Important

Properties Field: Adding the properties field organizes your input parameters, making the function easier for OpenAI to understand.

Required Field: Specifying which parameters are required is critical. This ensures that the API will fail fast if the necessary data isn't provided.

Building a Validation Function

To further prevent such issues in the future, consider implementing a validation function. This function can assure that only properly formatted functions are passed to the OpenAI API. Here’s an example of a validation function:

Conclusion

Integrating OpenAI's API into your chatbot can significantly enhance its capabilities, but it requires careful attention to detail in function definitions. By ensuring that your parameters are well-structured and validating them before sending them to the API, you can avoid common pitfalls like the InvalidRequestError. Don’t hesitate to experiment with the structure outlined above, and remember that testing each change can prevent future issues. Happy coding!
