openmediavault-wireguard :: Invalid RPC response

(I'm from Asia. Sorry for my poor English writing.)

Plugin : openmediavault-wireguard

Hello.

Whenever I try to save DNS settings for my wireguard clients in GUI, an error message "500 - Invalid RPC Response" shows up and nothing changes.

It recommended me check syslog, so I looked it over. There were suspicious things as follows;

Jan 19 23:23:47 user omv-engined[8778]: PHP Fatal error: Uncaught Error: Cannot unset string offsets in /usr/share/openmediavault/engined/rpc/wireguard.inc:272
Jan 19 23:23:47 user omv-engined[8778]: Stack trace:

Jan 19 23:23:47 user omv-engined[8778]: #4 {main}

Those lines repeat whenever I press "save" button after changing DNS settings. I wonder if it is only a problem for my instance or a kind of bug. Could someone tell me what to do?

What do you have in the DNS servers section?

There are 'disable', 'custom', and '1.1.1.1'.

What I wanted to do is changing 'disable' to '1.1.1.1'.

I found a typo. I will release a fix.

Thank you for your fast response.
