csv to json integer parse error using placeholders

so i have one csv file from there i’m parsing data in json, but there is integer conversion issue.

• def foo = ’10’

• string json = { bar: ‘#(1 * foo)’ }

• match json == ‘{"bar":10.0}’

• string json = { bar: ‘#(parseInt(foo))’ }

• match json == ‘{"bar":10.0}’

so i tried both ways to convert an string into integer but i am getting below error message:
"JSON parse error: Cannot deserialize value of type java.lang.Integer from String "(1 * total_amount)": not a valid java.lang.Integer value".
And 1000 is the value i’m giving in a csv file.

Above is my pom file.

{

"currency": "#(currency)",
"cptrid": "#(cptrid)",
"flexi1": "#(flexi1)",
"flexi2": "#(flexi2)",
"flexi3": "#(flexi3)",
"flexi4": "#(flexi4)",
"sys_id": "#(sys_id)",
"lead_id": "#(lead_id)",
"record_id": "#(record_id)",
"mode_of_payment": "#(mode_of_payment)",
"total_amount": "#(1 * total_amount)",
"instrument_ref": "#(instrument_ref)",
"instrument_date": "#(instrument_date)",
"bank_name": "#(bank_name)",
"branch_detls": "#(branch_detls)",
"receipt_no": "#(receipt_no)"
}

and above is the way i’m using placeholder for total amount.
