I’m trying to get monitoringType out of this content and to set it in the flow attributes for use later in routing to a particular elastic index

    [ {
  "Average_Wait_on_MRO" : 0.0,
  "CICSplex_Name" : "CP01PLEX",
  "Average_DB2_Time" : 0.039045,
  "Average_1st_Dispatch_Delay" : 2.0E-5,
  "Average_Wait_on_IC_Delay" : 0.0,
  "Average_wait_on_Redispatch" : 0.006552,
  "serviceclass" : "QTRANS",
  "Average_Response_Time_MS" : 5.961476,
  "Transactions_Total" : 17,
  "Interval_End_Timestamp" : 1240729190300000,
  "Average_Wait_on_Journal" : 0.007984,
  "monitoringType" : "PlexUtilisation",
  "@timestamp" : "2024-07-29T18:03:53.000Z",
  "Average_Wait_on_ENQ_Delay" : 0.0,

  "Average_Wait_on_FILEs" : 0.0,
  "Average_Dispatch_Time" : 0.207528,
  "Average_time_waiting_on_Adabas" : 0.05488,
  "cicsplex" : "CP01PLEX",
  "Transaction_ID" : "QADJ"
} ]```
: 
my processor looks like this

the intended attribute does appear in the output but has a value of "empty string set". Can anyone advise? I looked at some similar questions here but they did not help me.
