History detail api not working as expected on Camunda 7.16

I using the /history/detail api to list the variables used in an activity, I’m filtering by activityInstanceId but it returns an empty list when the activity is a Start Event, wtih another activities types is working as expected.

I calling the api this way

/history/detail?activityInstanceId={activityId}&deserializeValues=false

On camunda 7.10 the api works as expected, but on camunda 7.16 it returns an empty list for start events
