Thanks Frank! It is working now. Best!

Hi! I have the same issue that Nicolaij initially asked. But I do not understand the solution that replacing "im_uom_units" with "im_uom_unit" solve the problem. I am trying with postman a post request to a DEMO version of PO that we have and passing a json structure for the requested field of an invoice_item I tried the same way for creating an invoice and it works fine. Thanks in advance, Ramiro
