I'm writing a solution for managing my etsy store and am using Odoo online. I can successfully create an invoice via the API using my Make.com instance, however when I try to add the line items to the invoice, I get the error 1 , shown at the bottom of this post.

I'm sure it's a syntax issue, but I'm strugging to figure out what's wrong with it.

My research suggests the issue is the curly braces inside the invoice_line_ids array, however when I remove them, I end up with Error 2.

I'm using Odoo Online with Stuido, so custom code isn't possible.

Is this a language compatibility issue, because I've witten the API call in json?

Invoice Model: account.move

My code.

[
    {
        "partner_id": 14,
        "move_type": "out_invoice",
        "invoice_date": "{{now}}",
        "invoice_date_due": "{{now}}",
        "invoice_payment_term_id": 1,
        "journal_id": 8,
        "currency_id": 173,
        "invoice_line_ids": [{
                "product_id": 9056,
                "name": "Font: Julzy",
                "quantity": 1,
                "product_uom_id": 30,
                "price_unit": 10.00,
                "discount": 0,
                "account_id": 175,
                "tax_ids": [39]
        }]
    }
]

Error 1:
