Error 500 while submitting sales order - REST API

We’re using Rest APIs to create Sales Order, it’s on draft and I need to “submit”, if I tried to change the Sales Order status directly to “submit” it throws an error.

Body: form url encoded

action:Submit

The text editor for this forum provides a toolbar with buttons for correctly formatting code samples.

You are requesting that other members use their time to help you out, yet you do not use your time to learn those tools even enough to make it possible to read your question.

I have a lot of experience with the API and will make the effort to help you out, but only if I see you make the effort to format your question correctly.

For example, simply selecting your code and typing <ctrl>+<shift>+C, will produce:

{
    "naming_series": "001-002-.#########",
    "customer": "Diego Corral",
    "due_date": "2025-05-24",
    "taxes": [
        {
            "charge_type": "On Net Total",
            "account_head": "1.1.7.01.003 - Retencion IVA Terceros - LSSA",
            "rate": 12.0,
            "description": "Retencion IVA Terceros"
        }
    ],
    "items": [
        {
            "item_code": "BIODOX 2000 PPM 500ML",
            "qty": 1,
            "rate": 5000
        }
    ]
}

Change your docstatus value to 1 and change sales order status to “To Deliver and Bill”
