schema_validation_error
Invalid schema detected for function due to missing array items in the specified properties context.
This error has been identified and solved.
Reason
The 400 status error in the Azure OpenAI API, specifically the "Invalid schema for function" error, is likely due to several possible reasons:
Incorrect or Missing Schema
The error message suggests that the schema for the query_variations property is not correctly defined or is missing the required items field in the array schema. This indicates a mismatch between the expected and provided data structure[3,.
Invalid Request Parameters
The API might be receiving unrecognized or invalid request parameters. For example, using parameters that are not supported by the specific model or API version you are using, such as the issue with max_completion_tokens versus max_tokens for different models.
Payload Validation
The API may be strictly validating the payload, and any deviation from the expected format, including missing or incorrectly formatted fields, can result in a 400 error.
Header or Content-Type Issues
Although not directly related to the schema error, incorrect headers or a mismatch in the Content-Type header (e.g., expecting application/json but receiving something else) can also lead to a 400 error.
Solution
To fix the 400 status error in the Azure OpenAI API due to an "Invalid schema for function" error, you need to ensure the following:
Verify the schema definition: Ensure that the schema for the function includes all the required fields, particularly the
itemsfield in array schemas.Check request parameters: Use the correct parameters supported by the model and API version you are using. For example, use
max_tokensfor GPT-4 models andmax_completion_tokensfor the "o1" model series.Validate the payload: Ensure the payload is correctly formatted and includes all the required fields as specified in the API documentation.
Confirm headers and Content-Type: Make sure the
Content-Typeheader is set toapplication/jsonand other headers, such as the API key, are correctly configured.
By addressing these points, you can resolve the invalid schema and parameter issues causing the 400 error.
