Hello everyone,

I am currently seeking assistance with setting up a cron job in Odoo v16 on odoo.sh. 
Specifically, I want to create a script that adds an activity to all 'opportunities' in the CRM module that are not 'won', provided there is no existing activity.

Here is the script I have written so far:

leads = env['crm.lead'].search([('activity_ids', '=', False), ('probability', '

for i in range(0, len(leads), 10):
    batch_leads = leads[i:i+10]
    
    for lead in batch_leads:
        activity = env['mail.activity'].create({
            'res_id': lead.id,
            'res_model_id': env.ref('crm.model_crm_lead').id,
            'activity_type_id': 13,
            'date_deadline': datetime.datetime.today().strftime('%Y-%m-%d %H:%M'),
            'user_id': lead.user_id.id,
        })
        lead.write({'activity_ids': [(4, activity.id)]})

However, this script does not seem to work as expected. If anyone could provide guidance or suggestions to correct this script, I would greatly appreciate it.

Thank you in advance for your help and support.

Best regards
