       "boolean_3": true,
       "string_1": "1",
       "string_1_dup": "1",
       "string_2": "2",
       "integer_1": 1,
       "integer_1_dup": 1,
       "integer_2": 2

  }
}

Output

 
{{ fn.object_keys input.object,true }}


{{fn.object_keys input.object,"1"}}



{{fn.object_keys input.object,1}}



{{fn.object_keys input.object}}

["boolean_1","boolean_3"]


["string_1","string_1_dup"]



["integer_1","integer_1_dup"]



["boolean_1","boolean_2",
 "boolean_3","string_1",
 "string_1_dup","string_2",
 "integer_1","integer_1_dup",
 "integer_2"]
