### 📦 Package Version

0.3.26

### 🎞️ Framework Version

Litellm 1.58.2

### 🔎 Describe the Bug

@areibman At first it seemed it was an error from Litellm, but using Litellm independently it works fine.

Reference Script:
```
import os
import litellm
import agentops
agentops.init(default_tags=["Openai Example"])
messages = [{"role": "user", "content": "hello from litellm"}]
response = litellm.completion(
model="gpt-4o",
messages=messages
)
print(response.choices[0].message.content)
agentops.end_session("Success")
```

```
