im using ondelete parameter in several fields but somehow im getting this warning

WARNING prestaterreihza odoo.fields: Field certification.agreement.agreement_ids: unknown parameter 'ondelete', if this is an actual parameter you may want to override the method _valid_field_parameter on the relevant model in order to allow it

this is one of my warning field

    agreement_ids = fields.One2many('certification.agreement.line', 'agreement_id', string='Agreement Line', ondelete='cascade')

is there any requirement or something that needed to use the ondelete parameter? im currently in odoo 17

ondelete normally use for m2o and selection field, not o2m field. If you get warning for m2o field please check if your many2one field is store or not
