Hi All! I Have been trying to update my Existing Sales Order by Changing Some fields in the Existing line Item but it is giving me some errors

{"type":"error.SuiteScriptError","name":"TRANS_UNBALNCD","message":"Transaction was not in balance. Total = 700.0","id":"","stack":["anonymous(N/serverRecordService)","_put(/SuiteScripts/RestLet_Crude_Operation.js:211)"],"cause":{"type":"internal error","code":"TRANS_UNBALNCD","details":"Transaction was not in balance. Total = 700.0","userEvent":null,"stackTrace":["anonymous(N/serverRecordService)","_put(/SuiteScripts/RestLet_Crude_Operation.js:211)"],"notifyOff":false},"notifyOff":false,"userFacing":false}
Error: Error: {"type":"error.SuiteScriptError","name":"TRANS_UNBALNCD","message":"Transaction was not in balance.

This is my JavaScript Code

let data = {
      id: salesorder,
      recordtype: "salesorder",
      custbody_rr_startnewcontract: true,
      custbody_rr_contractpaymentmethod: "3",
      custbody_rr_billdaysinadvance: "15",
      opportunity: opportunity,
      cseg_property: property,
      custbodytransactionunit: unit,
      entity: entity,
      memo: memoforopp,
      custbody_agreement_tnumber: agreement,
      custbody_rr_contract_billing_day: contractBillingDay,
      salesrep: "8",
      department: "4",
      sublists: {
        item: {
          records: [
            {
              item: "29",
              line: 1,
              cseg_property: property,
              cseg_unit: unit,
              department: "4",
              description: memoforopp,
              custcol_rr_escpercent: "3",
              custcol_rr_escperiodmonths: "12",
              custcol_rr_contractendoftermaction: "4",
              custcolagreementline: agreement,
              custcol_rr_startdate: startDate,
              // custcol_rr_firstbillingdate: firstAutoBillDate,
              custcol_rr_nextescalationdate: nextEscalationDate,
              amount: license_fee,
              rate: license_fee,
            },
          ],
        },
      },
    };

And This is my suite Script Put request code

function _put(context) {
    doValidation([context.recordtype, context.id], ["recordtype", "id"], "PUT");
    try {
      var rec = record.load({
        type: context.recordtype,
        id: context.id,
        isDynamic: true,
      });
      for (var fldName in context) {
        if (context.hasOwnProperty(fldName)) {
          if (
            fldName !== "recordtype" &&
            fldName !== "sublists" &&
            fldName !== "id"
          ) {
            var fieldObj = rec.getField({ fieldId: fldName });
            if (fieldObj && fieldObj.type === "date") {
              rec.setValue(fldName, new Date(context[fldName]));
            } else {
              rec.setValue(fldName, context[fldName]);
            }
          }
        }
      }
      if (context.sublists) {
        var sublists = context.sublists;
        for (var sublistsId in sublists) {
          var records = sublists[sublistsId].records;
          for (var i = 0; i < records.length; i++) {
            if (records[i].type && records[i].type === "REMOVE") {
              rec.removeLine({
                sublistId: sublistsId,
                line: records[i].line,
                ignoreRecalc: true,
              });
              continue;
            }
            rec.selectNewLine({ sublistId: sublistsId });
            for (var sublistsFieldName in records[i]) {
              var sublistFieldObj = rec.getSublistField({
                sublistId: sublistsId,
                fieldId: sublistsFieldName,
                line: i + 1,
              });
              if (sublistFieldObj && sublistFieldObj.type === "date") {
                rec.setCurrentSublistValue({
                  sublistId: sublistsId,
                  fieldId: sublistsFieldName,
                  value: new Date(records[i][sublistsFieldName]),
                });
              } else {
                rec.setCurrentSublistValue({
                  sublistId: sublistsId,
                  fieldId: sublistsFieldName,
                  value: records[i][sublistsFieldName],
                });
              }
            }
            rec.commitLine({ sublistId: sublistsId });
          }
        }
      }
      var recordId = rec.save();
      return JSON.stringify(recordId);
    } catch (error) {
      return JSON.stringify(error);
    }
  }

Everything I've seen online about this seems to be surrounding Taxes. Either an Avalara issue, or something wrong with the item/customer tax setup https://www.reddit.com/r/Netsuite/comments/11eh3kw/transaction_not_in_balance_workflow_error/ https://docs.oracle.com/en/cloud/saas/netsuite/ns-online-help/section_164017180964.html#Troubleshooting-Common-Order[…]-Errors-in-NetSuite-Connector https://stackoverflow.com/questions/55855566/how-to-fix-trans-amts-unbalncd-when-trying-to-create-a-sales-record

you probably need to cut down your request to only update the field you really want
