Chat Completion with Image Input is not working

[IvanVohmin]

I was trying to use an image input in my chat completion, but it appears its not working at all.
My code:

client = OpenAIUnofficial()
response = client.chat.completions.create(
    messages=[{
        "role": "user",
        "content": [
            {"type": "text", "text": "What's in this image?"},
            {
                "type": "image_url",
                "image_url": {
                    "url": "https://upload.wikimedia.org/wikipedia/commons/thumb/d/dd/Gfp-wisconsin-madison-the-nature-boardwalk.jpg/2560px-Gfp-wisconsin-madison-the-nature-boardwalk.jpg",
                }
            },
        ],
    }],
    model="gpt-4o-mini-2024-07-18"
)
print("Response:", response.choices[0].message.content)``` 


and console return this error: 


```File "C:\Users\~\AppData\Local\Programs\Python\Python310\lib\site-packages\openai_unofficial\main.py", line 256, in create
    response = self.api_handler._make_request(
