The 'input' property is required but missing. Please provide the necessary data.

The 400 - Bad Request error in the OpenAI API, specifically with the message 'input' is a required property, indicates that the API request is missing a necessary parameter or has an invalid configuration. Here are some possible reasons for this error:

Invalid or Missing 'input' Parameter

• The API request may not include the required input parameter, which is essential for the API to process the request.

Incorrect Request Syntax or Configuration

• The request syntax or configuration might be incorrect, leading the server to be unable to understand the request. This could be due to malformed JSON, incorrect headers, or other syntactical errors.

Exceeded Request Limits or Invalid Model Parameters

• The request may violate the API's limits or constraints, such as specifying dimensions for a model that does not support them, or exceeding the allowed number of headers or tokens.

Server-Side Issues

• There could be server-side issues or changes in the API that are causing the error, such as new validation rules or temporary server-side problems.
