Dapr Zeebe worker binding doesn't handle user tasks

I’m using Dapr Zeebe bindings, but when I set io.camunda.zeebe:userTask as jobType in the binding configuration I get an error message:

 invalid header field name \"io.camunda.zeebe:formkey\"

Any idea if this is related to Zeebe, or rather to the Dapr binding itself?
