Error 500 when exporting

[luisjure]

Hi, I'm using I, Librarian on Arch Linux (currently 5.9.1 with PHP 8.0.7), and offline export is not working for me, I get this error:

Oops!
Call to undefined function Librarian\Http\Client\json_encode().

I don't know if it's a bug in I, Librarian, or something wrong in my installation. On Software details, everything is green.

Thanks for your attention.

Thank you for reporting this. It will be fixed in the next version.

[luisjure]

That's wonderful, thank you.

A related question: I intend to format my HD to reinstall a Linux distribution anew. Is it viable to simply compress the whole librarian directory under www and then uncompress it in the new system? Will that work?

Yes. All new files are stored in data directory, which must be writable by web server. You should include data in your daily backups.
