Tenho o seguinte JSON e estou tentando substituí- nulllo nilporque o Ruby não consegue compilá-lo.

Recebo o seguinte erro undefined local variable or method "null" for main:Object (NameError).

Descrição do alarme e unidade é null.

Como posso resolver isso?

jsondata = {
  AlarmName: "Zabbix PY 5XX - By Stage QA",
  AlarmDescription: null,
  AWSAccountId: "123456",
  NewStateValue: "ALARM",
  NewStateReason:
    "Threshold Crossed: 1 out of the last 1 datapoints [1.0 (06/11/21 12:16:00)] was greater than or equal to the threshold (1.0) (minimum 1 datapoint for OK -> ALARM transition).",
