any update on this?

[mfiedorowicz]

It's most likely due to NetBox 4.2.x which we don't support it yet as there were some breaking changes recently, it's high on our priority list things to fix.

Can report same issue using NetBox 4.1.11.
Any updates on this?

[dankotrajkovic]

Given the lack of reply on this issue, Diode feels like it is just in the experimental/testing days and not ready for other people to use it in production or for anything business critical.

[mfiedorowicz]

We are heads down making significant progress on major changes planned for our next release around the end of April, which will resolve these issues comprehensively. Our development efforts are centered on expanding support for NetBox object types and their attributes, while simultaneously enhancing the visibility of ingestion failures to streamline troubleshooting.

Same issue exist on 4.1.10, looking forward for the update hopefully at the end of april.

In Diode 1.0.0 we did a lot of breaking changes, have you installed everything from scratch like it was very first installation without any previous .env docker-compose.yaml, etc.? If not, I'd recommend to do so, including removing old docker volumes.
