As others have said, I suspect this was in error. However, there is still diplomatic work to be done even if this was an accident. Specifically, Russia must make a public statement confirming that this was in error, apologize unequivocally, and offer some form of meaningful compensation. The risk of no response is that it will make Poland and NATO look weak, and Russia is known for prodding and provoking to see what it can get away with. Better to nip this in the bud through diplomatic means to avoid any lingering doubts about Polish/NATO readiness to defend itself.
