Environment

  • Python version: 3.5.2
  • NetBox version: 2.4.7

Steps to Reproduce

This may not be perfectly reproducible as it depends on interaction with a live device. The issue I'm seeing is that a call for get_bgp_neighbors_detail() on a device will occasionally time out, prompting NetBox to raise an RpcTimeoutError exception. The full trace is included below.

Expected Behavior

The API should catch the exception and return an error message.

Observed Behavior

The exception is not caught, triggering a server error.
