After upgrading LiteLLM to version 1.82.3, editing any API key configuration (even for models without guardrails) triggers a false "Feature Unavailable" error claiming the guardrails feature requires a LiteLLM Enterprise license. The error persists despite having no guardrails configured in the application or environment. 4. Observe the error: {'error': 'This feature is only available for LiteLLM Enterprise users: guardrails...'}

Fix Plan

To resolve the "Feature Unavailable" error when editing API key configurations in LiteLLM version 1.82.3, we need to modify the license check logic.

• Update the guardrails feature check to only trigger when guardrails are actually configured.
• Modify the API key editing endpoint to bypass the enterprise license check when no guardrails are present.

Example code changes:

# Before
if model_has_guardrails:
    # Check for enterprise license
    if not is_enterprise_license():
        raise FeatureUnavailableError("guardrails")

# After
if model_has_guardrails and is_guardrails_enabled():
    # Check for enterprise license
    if not is_enterprise_license():
        raise FeatureUnavailableError("guardrails")

Verification

To verify the fix, follow these steps:

1. Apply the code changes.
2. Configure a model without guardrails.
3. Attempt to edit the API key via UI or configuration method.
4. The "Feature Unavailable" error should no longer appear.

Extra Tips

• Ensure that the is_guardrails_enabled() function correctly checks the guardrails configuration.
• Test the fix with different model configurations to ensure the issue is fully resolved.
