"an unknown value was passed to the validate function" when creating

[huntario]

Steps to reproduce
Products > click a product > add at least 1 rule > click save

Expected result
Rules saved on the product, product can now be used as a subscription

Actual result
"an unknown value was passed to the validate function" 400 is returned

Workaround
Downgrade with npm install [email protected] --save

Now the rules save as expected

Notes
Seems to be due to:
typestack/class-validator#1873

We may want to consider using version 0.13.2 until resolved

There are some properties on VariantPayload that are expected to be null at times

forbidUnknownValues is true by default after the last upgrade of the 'class-validator' library
