As reported in the community forum and reproduced locally, issuing a
QEMU guest agent command would lead to an error when proxying to
another node:
> root@pve8a2 ~ # pvesh create /nodes/pve8a1/qemu/126/agent/exec --command 'whoami'
> Wide character in die at /usr/share/perl5/PVE/RESTHandler.pm line 918.
> proxy handler failed: Agent error: Guest agent command failed, error was 'Failed to execute child process “ARRAY(0x55842bb161a0)” (No such file or directory)'
Fix it, by splitting up array references correctly.

Not sure if this is the correct place to fix it?
