This error has been identified and solved.
Reason
The error "Invalid chat format. Content blocks are expected to be either text or image_url type" with a 400 status code in the OpenAI API is likely due to the following reasons:
Incorrect Payload Structure: The API request payload might not be formatted correctly, specifically the
messagesfield. It may contain invalid or unsupported content types other thantextorimage_url.Unsupported Content Types: The API does not support the type of content you are trying to send, such as base64 encoded images, which may not be correctly recognized or handled by the API.
Non-Compliant Content Blocks: The content blocks within the
messagesarray may not adhere to the expected format, which requires each block to be either a text message or an image URL.
Solution
To fix the "Invalid chat format. Content must be either text or image URL type" error in the OpenAI API, you need to ensure your request payload is correctly formatted. Here are the key steps:
Use Supported Content Types: Ensure that each content block in the
messagesarray is either of typetextorimage_url.Correct Payload Structure: Verify that the
messagesfield is an array of content objects, each containing a validroleandcontentfield.Image URLs Instead of Base64: Use image URLs instead of base64 encoded images, as base64 images may not be supported in the current API version.

By adhering to these guidelines, you can ensure your API requests comply with the required format and avoid the 400 error.
