How to create an invoice in odoo via odoo-xmlrpc in node?

I am using https://www.npmjs.com/package/odoo-xmlrpc to create invoices in odoo 10. I can create an invoice, but i am unable to add invoice line_items to the invoice.

//connect to odoo
var odoo = new Odoo({
  url: "xxx",
  port: 443,
  db: "xxx",
  username: 'apiuser123456',
  password: 'xxx'
});


odoo.connect(function (err) {
  if (err) { return console.log(err); }
  console.log('Connected to Odoo server.');
  var inParams = [];
  inParams.push({
    'partner_id': 119,
    'account_id': 162,
    'invoice_line': [(0, '', { 'account_id': 162, 'name': "AAA", 'quantity': parseFloat('3'), 'price_unit': parseFloat('5') })]
  });
  var params = [];
  params.push(inParams);
  odoo.execute_kw('account.invoice', 'create', params, function (err2, value2) {
    if (err2) { return console.log(err2); }

  });
});

this code actually creates an invoice in odoo, but it does not add any line. I assume that the invoice_line attribute is somehow wrong but I fail to find the problem. I would have expected to see one line in the invoice with a total amount of 15 Eur.

Finally this is how i solved it:

1- adding the invoice_line_tax_ids as lined out above:

invoiceLines = [
  { 'account_id': 162, 'name': "Product A", 'quantity': 1, 'price_unit': 17, 'product_id': 1 },
  { 'product_id': 1, 'account_id': 162, 'name': "Product B", 'quantity': 1, 'price_unit': 17 }
]

-------------------
// partnerId is an id of an existing partner in odoo

function createInvoiceObj(partnerId, lineEntries) {

  inParams = [];
  params = [];
  inParams.push({
    'partner_id': partnerId,
    'account_id': 162,
    'invoice_line_ids': lineEntries
  });  
  params.push(inParams);
  odoo.execute_kw('account.invoice', 'create', params, function (err, invoiceId) {
    if (err) { throws('error during execution createInvoiceObj() ' + err); }
    return createTax(invoiceId);
  });
}

2- create tax entries for each line (find lineIds for invoice first)

function createTax(invoiceId) {
  var inParams = [];  
  var params = [];
  inParams.push([['invoice_id', '=', invoiceId]]);
  params.push(inParams);
  odoo.execute_kw('account.invoice.line', 'search', params, function (err, invoiceLineIds) {
    if (err) { return console.log(err); }
    invoiceLineId = invoiceLineIds[0];

    inParams = [];
    inParams.push(invoiceLineIds);
    inParams.push({ 'invoice_line_tax_ids': [[6, 0, [12]]] })
    params = [];
    params.push(inParams);

    odoo.execute_kw('account.invoice.line', 'write', params, function (err, value) {
      if (err) { return console.log('Error during execution ' + err); }
      return compute_taxes(invoiceId)
    });


  });
}

3- trigger tax calculation on invoice

function compute_taxes(invoiceId) {
    inParams = [];
    params = [];
    inParams.push(invoiceId);
    params.push(inParams);

    odoo.execute_kw('account.invoice', 'compute_taxes', params, function (err, result) {
      if (err) { return console.log(err); }  
      return invoice_open(invoiceId)
    });

  }

so the magix fix at the end was to call the compute_taxes function. However, i tried to take the next step and automatically confirm the invoice, but this still fails. I used the invoice_open workflow, but this shows no result:

function invoice_open(invoiceId) {

  var params = [];
  params.push(invoiceId);

  odoo.exec_workflow('account.invoice', 'invoice_open', params, function (err, value) {
    if (err) { return console.log("Error during execution " + err); }
console.log('Result invoice_open: ' + value); 
  });

}

this function always returns false but with no error message. The invoice state is not transsitioned to "confirmed" either.
