Can't send images to be analyzed to litellm models

When configuring a litellm that can analyze images like 'gemini-1.5-pro' or 'gemini-pro-vision' and send it an image file to be analyzed, it gets stuck into a loop trying to give an answer. Ultimately I have to restart de pod instance since the website becomes unresponsive.

Looking into it, the image file is being sent by pointing to a url :

I dont know if its related to hosting louis internally since it works when testing locally with the snippet code : https://litellm.vercel.app/docs/providers/gemini#sample-usage-1
