Approval for Additional Person Info returning null

Hello,

I am trying to configure approval rule for different type of additional person info, however whenever I submit a transaction it says that it contains null value.

I have tested different attributes in the approval rules and it all return a null value error, the attribute i have tested includes the following:

(Proposed Person Additional Person Info.result.peiAttributeCategory == "TEST")
(Proposed Person Additional Person Info.informationType == "TEST")
(Proposed Person Additional Person Info.result.informationType contains "TEST")
(Proposed Person Additional Person Info.peiInformationCategory == "TEST"
(Proposed Person Additional Person Info.peiInformationCategory == "TEST")
(Proposed Person Additional Person Info.peiInformationCategory == "TEST")
(Current Person Additional Person Info.result.informationType == "TEST")
