How to correctly pass sftp.args

[causalmask]

I'm having trouble correctly formulating the flags field to pass -o "sftp.args=-i /path/to/private_key" for example. I can get this to work correctly calling restic from the command line within the backrest docker container, but I can't seem to get it to work when attempting to configure it via the backrest web UI.

Is there some sort of special whitespace string handling or escape characters I need to be using?

I'm also not sure where to look for error logs. There's a popup error message at the top of the web UI but all it says is that it can't authenticate, so I'm not sure if the flags I pass are ending up in the right place.

-o sftp.args="-i C:/Users/myself/.ssh/id_rsa"

Maybe you are having my same problem 209 I was using a key with a passphrase, I ended up creating a new key without and it works also in the webUI
