Octoprint backup and restore problem because of the plugin.

[Fredy12335]

Hi!
I backed up my entire system with Octoprint backup. I replaced the SD card in the Raspberry pi. I reinstalled the all system. And after booting I tried to restore the system using the restore option of octoprint. This failed and I got the following error:

2021-11-15 17:54:15,281 - octoprint.plugins.backup - ERROR - Error while running restore
Traceback (most recent call last):
  File "/home/pi/OctoPrint/venv/lib/python3.9/site-packages/octoprint/plugins/backup/__init__.py", line 1260, in _restore_backup

UnicodeEncodeError: 'latin-1' codec can't encode character '\u2018' in position 32: ordinal not in range(256)

Steps to reproduce the behavior:

1. Install octolight.
2. Go to octoprint create backup
3. Make a new fresh system and try to restore.
4. See error

• OctoPrint or OctoPi version: 1.7.2
• Browser chrome
• Plugin version lastest
• PI 3b+

I "solved" the problem by deleting this line: {"key": "octolight", "name": "OctoLight", "url": "https://github.com/gigibu5/OctoLight"}, from the backup.zip: plugin_list.json file.
After this the restore is completed. (but the plugin is missed)

I attached the log
octoprint.log

I you need any infos/files let me know.
SFMBE.

Thanks!

Hey @Fredy12335,

Sorry this has been a while, I've just started looking into this issue.
I've been trying to get this issue to reoccur when restoring a backup but have been unable to do so.
I think because this has been an old issue and the OctoPrint environment has changed a bit since then, and I have started maintaining OctoLight and it is on a new repo, we might have to consider this closed for the moment.

However, if this is still a problem, I am more then happy to look into it some more.
