I got this with 2.1.20 when I copied from a (pyanodons) chipshooter machine to a ghost chipshooter machine.
I was trying this after copying from the chipshooter machine to the constant combinator did nothing (and no failure message either)

The mod Copy-Paste Recipe Signals (1.7.1) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event copy-paste-recipe-signals::on_entity_settings_pasted (ID 39)
copy-paste-recipe-signals/copy_from.lua:214: attempt to call field 'filter' (a nil value)
stack traceback:
copy-paste-recipe-signals/copy_from.lua:214: in function 'copy_from'
copy-paste-recipe-signals/control.lua:48: in function <copy-paste-recipe-signals/control.lua:35>

I have made an update, please check if the error remains

its no longer crashing and it copies the recipe to the ghost

but copying to a constant combinator is still doing nothing (and no message either)

What does your player configuration for the mod look like?

It is related to osha_smarter_pasting, when I deactivate it, pasting to constant combinators work. I opened a topic in osha_smarter_pasting so that the mod can hopefully stop suppressing the functionality of copy-paste-recipe-signals...

Would be a shame if only one of the 2 mods can work at the same time.
