"Could not convert value introductory to event format"

I am getting the subject error while simulating Free trial. It is in console. Free trial proceeds but I cant figure out the error meaning.

I could not find anything similar on the net or documentation.

iOS 18.1 StoreKit2 SwiftUI

Has anyone had similar issue that could advise ?
