Odoo 17, Problems with the soft argument in the post_ method

I made a development that runs on the _post method of Odoo 17, while I was developing it there was no problem, it was not until I installed it on a new base when this error started to occur at the time of making a product receipt in a purchase (my development has nothing to do with purchases, I never make an inheritance of the purchase module, I do not know why it happens at that time). Needless to mention that I always pass the “soft” argument when I call the _post method, I have never forgotten it, that's why I find the problem so frustrating.

The above server error caused the following client error:
RPC_ERROR: Odoo Server Error
    RPC_ERROR
        at makeErrorFromResponse (http://localhost:8069/web/assets/e226aa6/web.assets_web.min.js:2888:163)
        at XMLHttpRequest.<anonymous> (http://localhost:8069/web/assets/e226aa6/web.assets_web.min.js:2892:13)

This is my code:

def _post(self, soft):
    facturas_especiales = self.filtered(lambda factura: factura.factura_especial)
    for factura_especial in facturas_especiales:
        if not factura_especial.journal_id.facturas_especiales:
            raise ValidationError("El diario no está configurado para trabajar con facturas especiales")

move_types = ["fact", "fact_cambiaria", "fact_exportacion", "out_refund"]
por_certificar = self.filtered(
    lambda factura: factura.journal_id.facturacion_activa
    and (factura.tipo_factura in move_types or factura.factura_especial or not factura.tipo_factura)
    and not factura.certificada
)

for factura in por_certificar:
    if self.company_id.proveedor == "infile":
        infile.facturacion_electronica(self, factura)
    elif self.company_id.proveedor == "cofidi":
        cofidi.facturacion_electronica(self, factura)

continuar_movimientos = self.filtered(lambda fact: not fact.certificacion_error)
return super(AccountMove, continuar_movimientos)._post(soft)

Switching a keyword argument to a positional argument could be the problem here.

Odoo original (e.g. in account module):

def _post(self, soft=True):

yours:

def _post(self, soft):

The purchase module's call of that method probably calls it with a keyword argument which would explain the error message "TypeError: AccountMove._post() missing 1 required positional argument: 'soft'". That's because your method is expecting a positional argument, but the call is with a keyword argument.

Just change your method signature to the original one and everything should be fine.
