It looks like a lone ^ by itself in a character class is a syntax error:

What's happening here is that the ^ just negates whatever's inside the
brackets, so it doesn't count as a character. The right bracket ] has
to be the first character inside the brackets if you want it to be one
of the characters (unless it's escaped), so in this case it's counting
the ] as a character inside the brackets, not as the ending bracket.
Which explains the error message.
