Cant run sync or delete data source

[kbrown900]

Not sure exactly what is happening. I have a data source setup (just the github netbox/customizations repo for reports and scripts) but now with the new sync feature I tried to sync and it now says "AttributeError("'ManagedFile' object has no attribute 'data'")" and not sure what to do. I have the devicetype-library repo as well but that one worked perfectly fine. I tried to delete the Reports and Scripts repo thinking I could just recreate it but when I try to delete it, it now says;

<class 'django.urls.exceptions.NoReverseMatch'>

Reverse for 'managedfile' not found. 'managedfile' is not a valid view function or pattern name.

Python version: 3.12.3
NetBox version: 4.3.0
Plugins: None installed

Not sure if this is a bug from the new update (just released I know). I tried to do some searching but couldn't find anything that seemed relevant.

I have the same problem after upgrading to 4.3 with a local data source. If I recreate a new data source with the same path, it works fine. So I guess something didn't get migrated properly, I'm trying to find what it is.

Running the sync from nbshell shows the full stack trace:

>>> DataSource.objects.last().sync()
Traceback (most recent call last):

AttributeError: 'ManagedFile' object has no attribute 'data'

I tried to reproduce this in a fresh Netbox 4.3 docker container, but was unable to get that far. There — when I add a new local data source, there is no error but it doesn't recognize any of the script files inside.

I'm experiencing the same and have created an issue for this: #19381
