i using flowvariable display response , use dataweave same. flowvariable list. code works areas except 1 after replace operator in descriptions tag.the increment of index not occurred expected.is bug or poor programming practice. code listed below.

%dw 1.0 %output application/json    ---  errors:(  payload map  {  field_name:flowvars.fieldvariable[$$], filed_value:flowvars.valuevariable[$$], error_code:flowvars.errordescriptionvariable[$$], descriptions: flowvars.databasedescriptionvaribale[$$] replace /(field name)/ flowvars.fieldvariable[$$] replace /(data_type)/ flowvars.valuevariable[$$] replace /(})/ ""     } )  actual response follows:      {         "errors": [             {                 "field_name": "authorization",                 "filed_value": "abcdefghijklmnopqrstuvwxyz12345",                 "error_code": "400",                 "descriptions": "'[authorization]' invalid field in request header."             },             {                 "field_name": "base_currency_amount",                 "filed_value": "integer,null,number",                 "error_code": "400",                 "descriptions": "the value '[authorization]' not valid [abcdefghijklmnopqrstuvwxyz12345].]"             }         ]     }

the expected response 

{             "errors": [                 {                     "field_name": "authorization",                     "filed_value": "abcdefghijklmnopqrstuvwxyz12345",                     "error_code": "400",                     "descriptions": "'[authorization]' invalid field in request header."                 },                 {                     "field_name": "base_currency_amount",                     "filed_value": "integer,null,number",                     "error_code": "400",                     "descriptions": "the value '[base_currency_amount]' not valid [integer,null,number].]"                 }             ]         }
