Nitrokey 3 test failed after firmware upgrade to v1.3.1

I’ve done the upgrade with the latest nitropy and it was successful:

nitropy nk3 update                                                                                                                                                                                      127 ✘  1m 57s 

Do you want to perform the firmware update now? [y/N]: y

Please press the touch button to reboot the device into bootloader mode ...

During this update process the internal filesystem will be migrated!
- Migration will only work, if your internal filesystem does not contain more than 45 Resident Keys. If you have more please remove some.
- After the update it might take up to 3minutes for the first boot.
Never unplug the device while the LED is active!

See the release notes for v1.3.1:

Directly after the update, nitropy nk3 test or nitropy nk3 status may report an IFS or EFS error. This is expected and should be fixed by rebooting the device. Please open an issue or contact support if the error still occurs after a reboot.

Does this error still happen after the update?

Yes it was after update. But now I have removed the key then plugged it back and test passes.
