TCFv2: potential bug - null passed as argument instead of undefined or []

[jbartek25]

Type of issue

Bug or spec clarification

Description

The CMP API of our provider Onetrust doesn't work with Prebid when fetching consent inside an iframe. The reason is that Prebid sends parameter=null in the code here. Onetrust team argues that null is not a valid value and in order to declare no value for parameter it has to be set to either undefined or []. I checked the IAB TCFv2 spec and there's no explicit statement for or against null. Which end should be fixed? Prebid or the CMP?
