TypeError: Class constructor SocialPost cannot be invoked without 'new'

Version of FoalTS: 3.1.0

Hi,

I tried implementing https://foalts.org/docs/common/validation-and-sanitization#with-a-validation-class-class-validator in my foal project and I see the following error when I run my code.

[3:31:35 PM] Starting compilation in watch mode...

Is there any issue with FoalTS documentation? or framework? or am I missing something.

Thank you

Hi 👋

What version of class-validator do you use?

Could you share the code of SocialPost and the code that calls the hook?
