Originally created by @Dimaqa on GitHub (Sep 17, 2020).

Environment

  • Python version: 3.8.2
  • NetBox version: 2.9.3

Steps to Reproduce

After update to 2.9 i have the same issues described in #2621 but also on creating\updating objects.
And on top of that there can be WRONG user in change log for object change.

This is pretty hard reproduce intentionally. It happens in less than 1% of requests but still happens.

Expected Behavior

The operation should not produce a internal server error.

Observed Behavior

Thank you for opening a bug report. I was unable to reproduce the reported behavior on NetBox v2.9.3. Please re-confirm the reported behavior on the current stable release and adjust your post above as necessary. Remember to provide detailed steps that someone else can follow using a clean installation of NetBox to reproduce the issue. Remember to include the steps taken to create any initial objects or other data.

It happens with a big amount of requests, I've managed to reproduce it by running this code in parrallel for multiple /22 subnets

import pynetbox
import urllib3
import ipaddress
urllib3.disable_warnings()

network = ipaddress.IPv4Network('7.0.0.0/22')
nb = pynetbox.api(url='url', token='token')
nb.http_session.verify = False

for ip in network:
    nb.ipam.ip_addresses.create(address=str(ip), status='active')
    ad = nb.ipam.ip_addresses.get(address=str(ip), status='active')
    ad.update({'description':'test_desc'})

I've tested it on postgres 9.6 and 12 with local and remote installation

Also i've managed to get this error on bulk edition with 2000+ objects via netbox gui. That happened 2 times in a row, then completed succesfully.
Netbox exception was shown with the same stack trace in logs:

<class 'ValueError'>

For now i've monkey patched netbox/extras/signals.py with
if hasattr(instance, 'to_objectchange') and request.user.is_authenticated:
This ignores object changes, but at least i don't loose any data

Running into the same bug as well when updating multiple interfaces attributes on v2.9.9
Also using LDAP for authentication.

This was the response I received

HTTP 500 - {'error': 'Cannot assign "<SimpleLazyObject: <django.contrib.auth.models.AnonymousUser object at 0x7f4cbc4b46d8>>": "ObjectChange.user" must be a "User" instance.', 'exception': 'ValueError', 'netbox_version': '2.9.9', 'python_version': '3.6.8'}

A second request with the same data was successful.

Can we get someone who's experiencing the issue to volunteer to tackle this bug? It's going to be very difficult and time-consuming for someone else to reproduce and troubleshoot.

I've been digging into this the past few days and wrote a quick script that can mostly reproduce the issue.

This script will create a device, assign multiple interfaces concurrently using httpx, delete the device, and print the response.

pprint(bad)
print(f"Successful Requests {len(good)}")

Output

I'm seeing about 1-3 failed requests in batches of 100.

[{'error': 'Cannot assign "<SimpleLazyObject: '
           '<django.contrib.auth.models.AnonymousUser object at '
           '0x7fa2f89bf438>>": "ObjectChange.user" must be a "User" instance.',
  'exception': 'ValueError',
  'netbox_version': '2.9.9',
  'python_version': '3.6.8'},
 {'error': 'Cannot assign "<SimpleLazyObject: '
           '<django.contrib.auth.models.AnonymousUser object at '
           '0x7fa2ebc55f98>>": "ObjectChange.user" must be a "User" instance.',
  'exception': 'ValueError',
  'netbox_version': '2.9.9',
  'python_version': '3.6.8'}]

Successful Requests 98
Failed Requests 2

I'm not exactly sure how to troubleshoot this on the NetBox side but hopefully this script can be useful to someone with that knowledge so they can recreate the problem at least .

@mtbutler07 commented on GitHub (Nov 12, 2020): I've been digging into this the past few days and wrote a quick script that can _mostly_ reproduce the issue. This script will create a device, assign multiple interfaces concurrently using [httpx](https://www.python-httpx.org/), delete the device, and print the response. ```python3 #!/usr/bin/env python3.8 import asyncio import httpx import os from pprint import pprint TOKEN = os.environ.get("NETBOX_API_TOKEN") DEVICE_NAME = "TEST-SWITCH" DEVICE_MODEL = "WS-C2960-24PC-L" DEVICE_ROLE = "Switch" SITE = "TEST" async def main(): # setup session to NetBox async with httpx.AsyncClient( base_url="https://netbox", headers={ "Authorization": f"Token {TOKEN}", "Accept": "application/json", }, ) as nb_session: # create a test device create_device_response = await nb_session.post( url="/api/dcim/devices/", json=dict( name=DEVICE_NAME, device_type=dict(model=DEVICE_MODEL), device_role=dict(name=DEVICE_ROLE), site=dict(name=SITE), status="active", ), ) device_id = create_device_response.json()["id"] # create tasks for multiple interfaces interface_tasks = [ nb_session.post( url="/api/dcim/interfaces/", json=dict(name=intf, device=device_id, type="100base-tx"), ) for intf in [f"Ethernet0/{n}" for n in range(0, 100)] ] # schedule interface tasks to run concurrently on async event loop interface_responses = await asyncio.gather(*interface_tasks) # delete test device await nb_session.delete( url=f"/api/dcim/devices/{device_id}/", ) good_responses = [r.json() for r in interface_responses if r.status_code == 201] bad_responses = [r.json() for r in interface_responses if r.status_code == 500] return good_responses, bad_responses good, bad = asyncio.run(main()) pprint(bad) print(f"Successful Requests {len(good)}") print(f"Failed Requests {len(bad)}") ``` **Output** I'm seeing about 1-3 failed requests in batches of 100. ```console [{'error': 'Cannot assign "<SimpleLazyObject: ' '<django.contrib.auth.models.AnonymousUser object at ' '0x7fa2f89bf438>>": "ObjectChange.user" must be a "User" instance.', 'exception': 'ValueError', 'netbox_version': '2.9.9', 'python_version': '3.6.8'}, {'error': 'Cannot assign "<SimpleLazyObject: ' '<django.contrib.auth.models.AnonymousUser object at ' '0x7fa2ebc55f98>>": "ObjectChange.user" must be a "User" instance.', 'exception': 'ValueError', 'netbox_version': '2.9.9', 'python_version': '3.6.8'}] Successful Requests 98 Failed Requests 2 ``` I'm not exactly sure how to troubleshoot this on the NetBox side but hopefully this script can be useful to someone with that knowledge so they can recreate the problem at least .
