AttributeError when LiteLLM encounters API errors

[wanyichen06]

Bug: AttributeError - 'Exception' object has no attribute 'request'

Error

'Exception' object has no attribute 'request'

Environment

• LiteLLM + CrewAI + OpenRouter API
• Python 3.12
• Model: qwen/qwen3-8b

Problem

When OpenRouter API returns an error, LiteLLM's exception mapper tries to access exception.request attribute, but not all exception types have this attribute.

Root Cause

File: litellm/litellm_core_utils/exception_mapping_utils.py (lines 1444, 1519, 1578, etc.)

raise BadRequestError(
 ...
 request=original_exception.request, # ❌ Assumes .request exists
)

Impact

• Tool calls fail repeatedly
• Agent gets stuck in infinite loop
• Tasks never complete
• No retry mechanism triggered

Suggested Fix

Use safe attribute access:

request=getattr(original_exception, 'request', None), # ✅ Safe

Reproduce

1. Run agent with OpenRouter API
2. Wait for intermittent API error
3. Observe AttributeError in logs

Logs

2025-10-17 08:10:28 - stratus.tools.kubectl.nl2kubectl - ERROR - NL2Kubectl Tool failed with: 'Exception' object has no attribute 'request'

Error repeats every 2-5 minutes, agent never exits.

Hi @couragec, could this be for a branch not merged into the main as I don't see litellm in our repo
?
