ssh errors logged with level "debug" instead of "error"

[mcm1957]

Describe the bug
Errors ocurring during ssh commands are not visible, they are logged with .debug level only.

synology.0	2022-09-30 17:42:03.905	warn	System reboot
synology.0	2022-09-30 17:42:03.900	debug	*** ERROR : src: SSH Error: code: undefined message: sudo: 1 incorrect password attempt
synology.0	2022-09-30 17:42:03.899	debug	*** ERROR : src: SSH Error: code: undefined message: sudo: no password was provided
synology.0	2022-09-30 17:42:03.898	debug	*** ERROR : src: SSH Error: code: undefined message: Sorry, try again.Password:

Expected behavior
I would expect to see above error with severity "error" (and not severiyt "debug".

Versions:

• Adapter version: synology 2.1.9

DSM is 7.1, Command was "reboot"

Note:
The "function error" is a little bit confusing - it looks like every error is output as debug log if output at all:

   if (!~src.indexOf('getSongCover')){
        adapter.log.debug(`*** ERROR : src: ${src || 'unknown'} code: ${code} message: ${message}`);
    }

The routine "fucntion error" is called by functions which regular raise errors, i.e. polling the audiostation at a system without such a package installed. So error handling must become smarter to ignore those errors (as it does now) but raise real errors such as ssh password errors etc.
