Upgrading existing NetBox 4.3.7 to 4.4.0 fails when indexing extras.imageattachment

[bobbwest]

I have a working NetBox 4.3.7 without any plugins. Python 3.12.3

I've created a new NetBox 4.4.0 environment, restored the database from 4.3.7, and then run upgrade.sh.

It gets as far as indexing models, then fails on extras.imageattachment:

I'm guessing it has something to do with this commit: 6df0a02

However it seems that nobody else has run into this problem.

I've tried the upgrade in both a self-hosted environment, and a netbox-docker environment, with exactly the same outcome.

Can anyone point me in the right direction to get past this point?

Thanks for sharing the detailed traceback and steps you’ve tried.

Your error (KeyError: 'filename' while indexing extras.imageattachment) looks consistent with this bug report: “New image attachment index breaks if image name contains a slash” – #20236.

Quick things to try/workarounds:

• Check whether any image attachment names include a / (slash). If so, temporarily rename those images to remove the slash characters and run the reindex/upgrade again.
• If a fix has landed upstream for New image attachment index breaks if image name contains a slash #20236, moving to the next 4.4.x patch release should resolve the issue once it’s published.

If you can confirm that one or more image names contain a slash and that renaming them lets the reindex complete, that would align with #20236 and help others hitting the same edge case. Thanks!

That was indeed the problem. Thanks!
