[d90]

Plugin Version

0.4.10

NetBox Version

4.4.8

Python Version

3.12.3

Steps to Reproduce

Environment

• NetBox Version: 4.4.8
• Python Version: 3.12.3
• Plugin Version: 0.4.10 (issue appeared after upgrading from 0.4.6)

Custom Object Type Definitions

Based on my Netbox instance, here are the custom object types involved:

1. SLB Custom Object (slbs)

• Fields: name (string)
• host_list (many-to-many IP addresses)
• owner (FK to Contact)
• ssl_reencryption (boolean)
• vip (FK to IP Address)
• gslb
• aflex
• snow_ref
• location
• partition
• notes
• description

2. Health Monitor Custom Object (health-monitors)

• Fields: Name (string)
• method (choice: http/https)
• mtls (boolean)
• Port (integer)
• response_code (array)
• url_path (string)
• url_type (choice: GET/POST)

3. DVC Custom Object (dvcs)

• Fields: (domain validation control object)

4. SSL Profile Custom Object (ssl-profiles)

• Fields:
  • name (string)
  • cert_type (string)
  • comments (text)
  • dcv (FK to DVC custom object) - nullable
  • expiration_date (date)
  • health_monitor (FK to Health Monitor custom object) - nullable
  • renew_time (datetime)
  • slb_config (FK to SLB custom object) - required
  • sni_default (boolean)
  • snow_reference (string)
  • subject_alternate_name (string)

Reproduction Steps

1. Create an SLB custom object:
   POST /api/plugins/custom-objects/slbs/
   {
   "name": "test-example.rutgers.edu",
   "ssl_reencryption": true,
   "partition": "EI-PS",
   "vip": <ip_address_id>,
   "host_list": [<ip_address_id>]
   }
2. Note the returned ID (e.g., id: 100)
3. Create a Health Monitor custom object (optional):
   POST /api/plugins/custom-objects/health-monitors/
   {
   "Name": "test-example-https-monitor",
   "method": "https",
   "mtls": true,
   "Port": 443,
   "response_code": ["200", "301", "302"],
   "url_path": "/",
   "url_type": "GET"
   }
4. Note the returned ID (e.g., id: 50)
5. Create an SSL Profile linking to the SLB:
   POST /api/plugins/custom-objects/ssl-profiles/
   {
   "name": "test-example.rutgers.edu",
   "cert_type": "14404",
   "expiration_date": "2026-12-31",
   "slb_config": 100,
   "health_monitor": 50,
   "sni_default": true
   }
6. Attempt to edit and save the SSL Profile through the UI (API untested):
   - Modify any field (e.g., change sni_default to false)
   - Save the object

Upgrade NCO from 0.4.6 to 0.4.7, 0.4.8, 0.4.9, and finally 0.4.10.

Over time saving ssl profile causes the error. Restarting netbox fixes this for a period of time.

Expected Behavior

Saving ssl profiles causes no error.

Observed Behavior

The complete exception is provided below:

<class 'ValueError'>

Cannot assign "<Table2Model: dev-arc.rutgers.edu>": "Table3Model.slb_config" must be a "Table2Model" instance.
