I think the problem with journal, please check any account added to journal default accounts or not.

Here journal means payment method

Hi Mohammed, I have the same error and I checked the account.payment table and odoo created a record with the payment    but still have this error. what else could be the error?

Thanks in advanced!

Hi, 

If you are creating invoice, you should take note that the account.invoice has a compulsory field of account_id and the account.invoice.line has a compulsory field of account_id, but of them must have a value when trying to create.

The payment module, just has journal, so you might not really have to worry about account_id, so your account_id issue is coming from account.invoice and account.invoice.line

This might help:

account_inv = self.env['account.invoice'].create({
    'partner_id': partner_id.id,
    'journal_id': journal_id.id,
    'origin': sale_order.name,
    'account_id': your_account_id.id,
    'invoice_line_ids': [(0, 0, {'product_id': product_id, 'name': name,
                                 'product_uom_qty': product_uom_qty,
                                 'price_unit': price,
                                 'account_id':account_id.id,

                                 }
                          )],

})
