I don't know if it is a bug or 'feature' but Session Propoerties & User Properties in mashup events are no more available. We migrated to the 8.4.2 version and most of our mashups are broken.
I didn't find any Realese Notes either opened tickets about this issue. Any ideas when it will be fixed?
Please open a support ticket for this.
