Dalle via Litellm

[Phlasse]

Hi there,

first off, thanks for the great work. I have been playing around with librechat for quite some time now.
I am using it together with litellm as there is no native support for langfuse yet (afaik).

So far I understood, that I can send plugins (e.g. dalle) via OPENAI_REVERSE_PROXY env into litellm, but this only captures the preparation of the dalle request. When the plugin / dalle function is triggered, it still goes directly to openai and therefore does not find its way into litellm.

I tried the DALLE_REVERSE_PROXY env, but this just returns a 500 error. Unfortunately, I cannot see the actual request url in the logs, so I cannot see, wether I made an error there.

for DALLE_REVERSE_PROXY I already tried:

http://litellm:4000
http://litellm:4000/v1
http://litellm:4000/v1/images
http://litellm:4000/v1/images/generations
http://litellm:4000/images/generations

no option worked. This "http://litellm:4000" worked perfectly fine as OPENAI_REVERSE_PROXY.

I am happy for any help or push into the right direction.

Best regards.
