[Bug]: Calls to Azure assitants api with vision capabilities cause api server to crash

[thingersoft]

What happened?

If you configure an Azure assistant with vision capabilities (es: gpt4o) and send it a message with images attached than the api server instantly crashes.
I know knowledge retrieval isn't currently available for Azure assistants but image attachments shouldn't trigger it.

Steps to Reproduce

1. Configure an Azure assistant with vision capabilities (es: gpt4o)
2. Send a message to the assistant with an image attached

What browsers are you seeing the problem on?

I fixed the crashing behavior, but I'm not sure if this would work correctly as is, since you would specifically need to use gpt-4-vision-preview for this to work. gpt-4o supports vision but it would only work correctly when using azure assistants v2. Currently, it's not planned to integrate V2 in favor of Agents native to LibreChat, through which you could use Azure more intuitively #3607
