@ApiQuery does not work properly with fastify

[maioradv]

Is there an existing issue for this?

Current behavior

I'm passing an object in the query params using the validation pipe that consent only whitelisted properties

?filters[name]=asc

that's the message that returns me using fastify
["property filters[name] should not exist"]

but with express works well

Minimum reproduction code
