Kitten @ kitten clipboard/icat etc. doesn't run

[AniAggarwal]

Describe the bug When running kitten @ and then a specific kitten, the following results.

$ kitten @ --to=$KITTY_LISTEN_ON kitten clipboard

The use case is to use the --to flag with a kitten clipboard, using kitten @ rather than kitty @ for use on a remote machine.

To Reproduce Steps to reproduce the behavior:

1. Run kitty @ kitten clipboard or kitten @ kitten clipboard or with the icat kitten.

   
   ❯ kitten @ kitten clipboard

**Additional context**
Using no config doesn't allow this to work since remote control is disabled. 
Running as follows:
`kitty --config NONE -o allow_remote_control=yes` results in same errors:

You want to use the clipboard kitten you simply do

kitten clipboard

It works fine over SSH. https://sw.kovidgoyal.net/kitty/kittens/clipboard/

[AniAggarwal]

I'd like to use kitten clipboard as my neovim clipboard so that I can use it over ssh like normal but neovim doesn't let you use kitten clipboard calls through it since it doesn't set up a tty. Based on the previous threads you had recommended using the --to flag and use listen on so thats why I am attempting to use this in this manner.

Is there a better way to make clipboard over ssh with (neo)vim work?

[kovidgoyal]

Use up to date neovim where it supports OSC 52 natively which works over ssh natively.

[AniAggarwal]

The issue with OSC 52 is that it doesn't seem to actually copy across my ssh for whatever reason from remote machine back to local machine buffer. AFAIK it seems like it isn't a fully fledged clipboard provider and I can't expect more from it? I realize I could setup something like lemonade but I'd like to stay in the kitty ecosystem if possible since it does practically everything else so well :)

[kovidgoyal]

The clipboard kitten also uses OSC 52. So there is no way it can not be working, if the kitten is working. If it isnt working in nvim you need to ask the nvim developers for help.

[AniAggarwal]

Huh, I didn't know that. Got it. Perhaps the error I encountered though should have a more friendly error message so others know not to use the kitten @ in this way? Thanks again.
