Can a company make you pay for a mistake you made, when working as a freelancer?

For context, I work as a Project Manager for a content writing company, it's a freelance position, every position is freelance in the company.

I made a mistake in one of the projects, and according to them, cost them a lot of money. They're asking me to deduct money from my invoice due to that mistake.

Is this even legal?

Any answer is appreciated, I don't know much about freelancer rules.
