The input for 'tools' or 'functions' is expected to be an array, but a different data type was provided. Please ensure the input adheres to the required schema.

The 400 status error you are encountering with the Azure OpenAI API could be due to several reasons:

Incorrect Parameter Usage

The error message suggests that the parameter structure or type is incorrect. For example, if you are using parameters that are not recognized by the specific model or API version you are calling, it can result in a 400 error. This is evident in cases where using max_completion_tokens with certain models like GPT-4, which require max_tokens instead, leads to errors.

Malformed Resource ID or Incorrect Configuration

If the resource URI or the configuration for the managed identity is incorrect, it can lead to authentication errors and subsequently result in a 400 status code. This includes issues such as incorrect resource IDs or missing necessary roles assigned to the managed identity.

Content Filtering Policies

Azure OpenAI has content filtering policies that can filter out prompts that violate certain guidelines. If your request triggers these policies, you may receive a 400 error indicating that the response was filtered due to content management policies.

Request Argument Errors

If the request arguments are not correctly formatted or if they do not match the expected type (e.g., expecting an array but receiving an object), it can lead to a 400 error. The error message you provided indicates an issue with the parameter not being of the correct type ('tools' not being an array)[Your Query].
