Server Error Netbox Custom Objects 0.4.0 Imports

[d90]

Plugin Version

0.4.0

NetBox Version

4.4.1

Python Version

packaged NetBox Community v4.4.1-Docker-3.4.1

Steps to Reproduce

Update Netbox custom objects from 0.2.0 to 0.40. follwing #213.
Boot up netbox and create custom objects with fields
Click import on the newly created object.

Expected Behavior

When I hit the import button I'm presented with the import UI

Observed Behavior

In my dev\test environment I get the following Server Error when I try to use the import function on a custom object. This same instance had earlier versions of netbox custom objects. I followed these instructions to get the application to boot with 0.4.0 enabled. After fully upgrading to 0.4.0 I created new custom objects, 2 of which i see the error. I tried creating a new custom object (a 3rd one since the update), which I CAN import to. I'm not sure what the difference is here.

Prior to General Availability (0.4.0) the guidance was that data created in the Custom Objects plugin was not guaranteed a clean upgrade path until after GA. I'm sorry but we can't support or troubleshoot issues arising from data created in the pre-release schema of the plugin.

[d90]

It wasn't created in the pre-release schema. This data was created AFTER upgrading to 0.4.0.

@d90 Could you please provide the full traceback of the error? A single line is not very helpful in tracing down the issue. Thanks —
