[Bug]: Internal Server Error, 'NoneType' object is not iterable

[enricolucakindle]

What happened?

I set up LiteLLM using the coolify service.

First of all, i had to remove from the config:

service_callback: ["prometheus_system"] success_callback: # - "langfuse" - "prometheus" failure_callback: # - "langfuse" - "prometheus"'

otherwise it would log that this is an enterprise feature.

After login or when reloading the page /ui/?userID=default_user_id&page=api-keys

i receive the following error

{"error":{"message":"Internal Server Error, 'NoneType' object is not iterable","type":"internal_server_error","param":"None","code":"500"}}

Relevant log output
