Issue with Device Recovery in Latest OpenWISP2 – Possible Bug

[Logunath K]

Hi team,

               I would like to report a potential issue I encountered while using the latest version of the OpenWISP2 application. Below are the steps I followed and the observations:

1. I registered a device and it was working correctly.
2. I deactivated the device using the dropdown list and waited until the device status updated to "Deactivated".
3. After that, I deleted the device.
4. Later, I used the “Recover Deleted Devices” option in the OpenWISP2 application to restore the device.

Issue Observed:
After recovery, the device came back online and appeared to be working.However, in the OpenWISP2 logs, I noticed an error (screenshot attached). It seems some device data was lost during this process.

Could you please confirm whether this is a known bug or an expected behavior? Also, I would appreciate any guidance on how to prevent this issue or resolve it properly.

Please find the screenshot of the log error attached for your reference.

From what you wrote it doesn't look too worrying.

It looks like it originated from the firmware-upgrader module in "auto_add_device_firmware_to_device".

If you find a way to replicate it consistently in a development environment based on the firmware-upgrader module you're welcome to open a bug report, find the instructions for setting it up here: https://openwisp.io/docs/dev/firmware-upgrader/developer/installation.html

Bug reports can be submitted here: https://github.com/openwisp/openwisp-firmware-upgrader/issues.

Best regards

Hi,

     Thanks for the instructions. I'll work on replicating the error in the development environment and will open a bug report if I succeed.
