APAR status

• Closed as program error.

Error description

• The following REST APIs return the error “CWTBG0535E: Property
  'key1' could not be set on a variable of class 'Map'.” if a JSON
  object such as ä“key1”:”value1”,”key2”,”value2”ü is specified
  for a variable of type Map as part of the request data:
  
  - Start Process (/rest/bpm/wle/v1/process?action=start)
  - Set Task Data (/rest/bpm/wle/v1/task/ätaskIdü?action=setData)
  - Finish Task (/rest/bpm/wle/v1/task/ätaskIdü?action=finish)
  

Local fix

Problem summary

• JSON input data is converted correctly only if the variable is
  persisted as an instance of class TWObject. The conversion fails
  if the variable is persisted as an instance of a complex java
  type like java.util.Map.
  

Problem conclusion

• A fix is/will be available that allows you to pass an input
  parameter of type Map for REST APIs.
