Error in setting line fields in inventory transfer through SS 1.0

Question

I m trying to create an inventory transfer from a suitelet and on setting line fields, system is giving me the error to set at least one item. ERROR:

"code\":\"USER_ERROR\",\"details\":\"You must enter at least one line item for this transaction"

my code is as follows:

datamap object for lines reflecting as follows:

[{"item":"12482","fromLocation":"17","qtytoadj":"1","amount":null,"remarks":null,"project":"6621","projectTask":null,"matReqId":"8636","itemtype":"InvtPart","islotitem":"F"}]
//creating inventory transfer record
    var createInvTrans = nlapiCreateRecord('inventorytransfer');
    //Body fields
    createInvTrans.setFieldValue('subsidiary', subsidVal);
    createInvTrans.setFieldValue('location', 17);
    createInvTrans.setFieldValue('transferlocation', 10);
    createInvTrans.setFieldValue('custbody21', projectFld);
    
    var toData = dataMap[matRecs];
    nlapiLogExecution('debug', 'toData', JSON.stringify(toData))
    nlapiLogExecution('debug', 'toData.length', toData.length)
    
    for (var i2 = 0; i2 < toData.length; i2++) {
      createInvTrans.selectNewLineItem('inventory');
      createInvTrans.setCurrentLineItemValue('inventory', 'item', toData[i2].item);
      createInvTrans.setCurrentLineItemValue('inventory', 'adjustqtyby', toData[i2].qtytoadj);
      createInvTrans.commitLineItem('inventory');
    }
    //sumbitting inv Adj
    var invTrans = nlapiSubmitRecord(createInvTrans, true, true);

Can anyone help me is there anything that i m doing wrong? because my Data in datamap is right as required but wherever execution reaches to set lines, the error comes.

You're using the wrong mode. You're using the dynamic mode sublist operations with a non-dynamic record.

You could do initialize the transfer as dynamic :

var createInvTrans = nlapiCreateRecord('inventorytransfer', {recordmode: 'dynamic'});

or use the server side api for the sublist:

for (var i2 = 0; i2 < toData.length; i2++) {
  createInvTrans.setLineItemValue('inventory', 'item', i2 +1, toData[i2].item);
  createInvTrans.setLineItemValue('inventory', 'adjustqtyby', i2+1,  toData[i2].qtytoadj);
}
