When validating an instance that contains a required slice, the error below occurs. Sushi and genonce do not give any errors.

The profile is on Appointment and the slice on participant:

* participant ^slicing.discriminator.type = #type  
* participant ^slicing.discriminator.path = "$this.actor.resolve()"        
    
* participant ^slicing.rules = #open
* participant contains healthcareservice 1..*
* participant[healthcareservice] ^short = "HealthcareServices involved in appointment"
* participant[healthcareservice].actor 1..1
* participant[healthcareservice].actor only Reference(HealthcareService)

Is it possible for you to include the instance you validated against + the StructureDefinition?

[barbrovessman]

Sure! The attached Appointment is part of a Parameters instance being validated, but hopefully this is enough to replicate the issue
