Hello,

Thank you for your PR. Unfortunately I will not continue to maintain this repo.

For the story:

• Since Netbox 4.x use openapi and not swagger, I tried to rollback my code to use the go-netbox provided by the community https://github.com/netbox-community/go-netbox. However this repo is not really maintained... PR opened since Nov 15th 2024 : Fix choices count netbox-community/go-netbox#191
• So I decided to fork again this repo and create my own lib : https://github.com/smutel/go-netbox-community. You can try the branch called work to test the last version
• This library is developed with the migration of my netbox provider to use openapi : https://github.com/smutel/terraform-provider-netbox/tree/UpdateForNetbox4

I don't how you use this lib but if you can try go-netbox-community and tell me if you encounter issues, it will be great ...
