RCRD_DSNT_EXIST while creating user event script with aftersubmit function - netsuite

Question

I'm trying to write a user event script which loads the current record and populates a line item value through search after submit record. But, it is giving an error RCRD_DSNT_EXIST, even though the record exists.
function afterSubmit_SO(type){
try
{
//var record_type = nlapiGetRecordType();
var recordID = nlapiGetRecordId();
var context = nlapiGetContext();
var recordOBJ = nlapiLoadRecord('salesorder',recordID);
var source = context.getExecutionContext();
if(source == 'userinterface')
{
var line_count = recordOBJ.getLineItemCount('item');
nlapiLogExecution('DEBUG', 'line count ', line_count);
for(var i = 1; i <= line_count; i++)
{
var itemID = recordOBJ.getLineItemValue('item','item',i);
nlapiLogExecution('DEBUG', 'item ID', itemID);
var filter = new Array();
filter[0] = new nlobjSearchFilter('internalid', null, 'is', itemID);
var columns = new Array();
columns[0] = new nlobjSearchColumn('custitem_web_market_availability');
var a_search_results = nlapiSearchRecord('item',null,filter,columns);
if(a_search_results)
{
for(var x = 0; x < a_search_results.length; x++)
{
var item_web_availability = a_search_results[x].getText('custitem_web_market_availability');
nlapiLogExecution('DEBUG', 'value', item_web_availability);
}
} recordOBJ.setLineItemValue('item','custcol_web_item_availability',i,item_web_availability);
}
var submitID = nlapiSubmitRecord(recordOBJ, true, true);
}
}
catch(exception)
{
nlapiLogExecution('DEBUG','Exception Caught ','' + exception);
}
return true;
}```

It could be that your script is executing on the delete operation. I did not see any checking for this in the code you provided. If it is a delete operation then the after submit user event script wont be able to load the deleted record, this is why you get the error.
The type parameter of your afterSubmit function should contain the operation type. You can something like if (type == 'delete') { return true;} at the top of your script.
