create record oddorpc flutter - database

Question

after adding all form data the user clicks on submit then this method calls and it is using the odoo_rpc 0.5.1 package to create a record by the app but it is a thorough exception.
createPayment(
String paymentDate,
paidViaListVal,
paymentTypeListValue,
expenceAccListVal,
partyPaymentvalue,
amountPaid,
paymentReference,
paymentNote) async {
if (_formKey.currentState!.validate()) {
// logger.d(
// 'paymentDate = $paymentDate paidViaListVal = $paidViaListVal paymentTypeListValue = $paymentTypeListValue expenceAccListVal = $expenceAccListVal partyPaymentvalue = $partyPaymentvalue amountPaid = $amountPaid paymentReference = $paymentReference paymentNote = $paymentNote');
paidViaListVal = paidViaListVal.toString().trim().split('-');
paidViaListVal = paidViaListVal[0];
expenceAccListVal = expenceAccListVal.toString().trim().split('-');
expenceAccListVal = expenceAccListVal[0];
partyPaymentvalue = partyPaymentvalue.toString().trim().split('-');
partyPaymentvalue = partyPaymentvalue[0];
if (paymentTypeListValue == 'Party Payments') {
paymentTypeListValue = 'party_payment';
} else {
paymentTypeListValue = 'expense';
}
if (expenceAccListVal == 'Select') {

}

}
if (amountPaid == '') {
amountPaid = 0;
}
if (paymentReference == '') {
paymentReference = false;
}
if (paymentNote == '') {
paymentNote = false;
}
logger.d(
'payment_date = $paymentDate payment_account = $paidViaListVal payment_type = $paymentTypeListValue expense_account = $expenceAccListVal party = $partyPaymentvalue amount_paid = $amountPaid paymentReference = $paymentReference payment_note = $paymentNote');
