Unable to "Delete all devices": Input should be a valid list

[Creat]

What installation are you running?

Production (netalertx) 📦

Is there an existing issue for this?

• I have searched the existing open and closed issues and I checked the docs https://docs.netalertx.com/

The issue occurs in the following browsers. Select at least 2.

• Firefox
• Chrome
• Edge
• Safari (unsupported) - PRs welcome
• N/A - This is an issue with the backend

Current Behavior

When navigating to Maintenance/Tools and clicking "Delete all devices", it just pops up a message in the browser:
Error: Validation Error: Input should be a valid list
No devices are deleted.

Expected Behavior

I expect all devices to be deleted.

Steps To Reproduce

I have tried to find a way to clear all devices, but with no success. So for me this always happens, 100% of the time. I did try disabling a few plugins (specifically OMDSDNOPENAPI), but that didn't change anything either.

This is basically a test-installation to see if it does what I need. It's relatively bare bones and not a lot of settings have been adjusted. Not quite "stock", but very close.

Relevant app.conf settings

LOADED_PLUGINS=['ARPSCAN','CSVBCKP','DBCLNP','DIGSCAN','MAINT','NEWDEV','NBTSCAN','NSLOOKUP','NTFPRCS','SETPWD','SMTP','SYNC','VNDRPDT','WORKFLOWS','UI','CUSTPROP','OMDSDNOPENAPI','INTRNT','ICMP','SNMPDSC']

Hi @Creat ,

Thanks for the report.

You can use the following workaround whilst this is being fixed:

1. Navigate to Maintenance -> Multi-edit
2. Select all devices (by licking the ✔ icon)
3. Enter the (unknown) value in the Name field
4. Click the save 💾 icon next to the field
5. Navigate to Maintenance -> Tools
6. Click Delete (unknown) devices

Edit:

Actually, this should work also:

1. Navigate to Maintenance -> Multi-edit
2. Select all devices (by licking the ✔ icon)
3. Click "Delete selected devices"

There are other workarounds too, so let me know if you have issues.

This should be fixed in the next release.
It would be great if you could test the ghcr.io/netalertx/netalertx-dev Docker image in ~15 minutes (or once the latest GitHub Action finishes).

⚠️ Please back up everything first, or ideally spin up a separate container with its own DB and config (a copy of your current setup), as database changes may occur.

After updating:

• Click the 🔄 refresh button in the blue header at the top
• Hard refresh your browser cache (shift + reload) to force js and css files reload

Disclaimer: Running the dev container long-term may lead to data loss, as upgrade paths are not guaranteed.

Thanks in advance,
j

Since my own installation was just a basically empty & new installation, I just reset it by setting the flag to start with an empty DB and settings every time in the compose file (restart cont, disable flag again, restart once more). I did lose my settings with that of course, but again, wasn't much in there yet either (and I do have a backup, just in case).

So I would've loved to test the fix in the dev branch, but I'm already past the point where I can. Sorry...
