skipMissingProperties issue?

[erangh]

Hi,
I am using GQL server and use class-validator to perform validation on the query/mutation input.

It appears that when I upgrade from version 0.13.2 to 0.14.0, I am getting the following error:
{
"unknownValue": "an unknown value was passed to the validate function"
}
The error is given on non mandatory leaf field defined on inner object (level 4).
When debugging the code, it looks like it use skipMissingProperties option.
Can someone assist?

forbidUnknownValues defaults to true in 0.14.0 onwards. If this breaks your validation, please consider refactoring your code so that this problem doesn't occur. You are possibly risking some unknown data sneaking into your program undetected, so to speak.

If that doesn't fix it for you, see #1873

Hi Brage,
Thank you for the reply.
I adjust my code to make class validator be aware the classes that it failed on and the optional fields. so now everything is working well with forbidUnknownValues = true

Note that I didn't understood the meaning of this flag from the documentation, maybe worth explaining it as now this is the default.
