Describe the problem/error/question
We are trying to - with n8n - create a draft invoice in odoo that has some line items on the invoice. What we achieved so far is:
- Read some customer data from a database and based upon that information create a draft invoice for that customer (empty) → Success
Now - as soon as I want to add some line items (meaning: e.g. a Product that i want to invoice or any other “line” for that matter) I get the following error:
NodeApiError: Wrong value for account.move.invoice_line_ids: [(0, 0, {
'product_id': 11,
'quantity': 1,
'price_unit': 100.00,
'account_id':1,
})]

Information on your n8n setup
- **n8n version: 1.20.0
- **Database (default: SQLite): PostgreSQL
- n8n EXECUTIONS_PROCESS setting (default: own, main):
- **Running n8n via (Docker, npm, n8n cloud, desktop app): LCX-Container
- **Operating system: Linux
My guess would be that we are not providing the correct format, amount, … of parameters in the account.move.invoice_line_ids, but i can not find any helpful comment on how to correctly put it into n8n to get it going.
Any support / ideas – much appreciated!
Best regards, Martin
