[Bug]: User Key Add Error: `'str' object has no attribute '_meta'`

[gpmidi]

NetBox Secrets plugin version

v1.9.0

NetBox version

v3.6.7

Steps to Reproduce

1. Go to User Key | Add New Key
2. Enter a RSA key - I had the problem with both 4k and 8k keys. Didn't test others.
3. Click "Create"
4. Get error page with 'str' object has no attribute '_meta'

Might be related to Netbox issue 7474

Expected Behavior

A new public key should be added for my user

Observed Behavior

<class 'AttributeError'>

'str' object has no attribute '_meta'

Python version: 3.11.6
NetBox version: 3.6.7
Plugins: 
  netbox_cable_labels: 0.0.3
  netbox_dns: 0.21.8
  netbox_inventory: 1.5.2
  netbox_secrets: 1.9.0

Thank you for opening a bug report. I was unable to reproduce the reported behavior on NetBox v3.6.7. 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.

I'm seeing the same issue on the newest versions of netbox-docker and netbox-secrets.

Just created a completely bare, fresh install with no objects other than my user. Tried with 2048 and 4096-bit keys and got the same message as OP.

Unless someone provides us the steps to reproduce this bug, it's not possible for us to find which condition might have caused this. We too use our plugin and have not yet encountered it anywhere.

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.

Rather than setup instructions, please provide the steps that caused the issue in the first place. I did exactly as you outlined in your setup instructions and I cannot reproduce the issue. So, I'm left to believe that this is a user error for now as you are failing to provide the steps.
