Automate System Import with script

[julia65]

Hi! I am trying to automate the system import process. Essentially, from the servicenow catalog I want the user to be able to attach an excel spreadsheet, have it loaded into a data source, then a staging table, then transform it to a maintenance table... but ultimately I just want each row in the excel spreadsheet to be a new record created in the maintenance table. 

The script I have successfully creates a data source for the spreadsheet but doesn't import the data into the staging table or the maintenance table. I was wondering if anyone else stumbled across this issue? Below is what I have and I'm doing this through Record Producer.

Additionally, for every attachment I get

var transformMapSysIDs = 'ca72a6091b5b25187a74ca262a4bcba3';

//loads excel into datasource

current.name = gs.getUserName() + " Import at: " + new GlideDateTime();

current.import_set_table_name = 'x_inprf_contract_0_staging_table';

current.file_retrieval_method = "Attachment";

current.type = "File";

current.format = "Excel";

current.header_row = 1;

current.sheet_number = 1;

dsr = current.insert();

gs.info('Data Source' + dsr);

GlideSysAttachment.copy('sc_req_item', current.sys_id, 'sys_data_source', dsr);

//imports data into staging table

var ds_sys_id = dsr;

var dataSource = new GlideRecord('sys_data_source');

dataSource.get(ds_sys_id);

var loader = new GlideImportSetLoader();

var importSetRec = loader.getImportSetGr(dataSource);

var ranload = loader.loadImportSetTable(importSetRec, dataSource);

importSetRec.state = "loaded";

importSetRec.update();

var transformWorker = new GlideImportSetTransformerWorker(importSetRec.sys_id, transformMapIDs);

transformWorker.setBackground(true);

transformWorker.start();
