Hi,

I try to automate the creation of reccuring invoices. I manage to create the invoice, send it by mail using my template with the pdf attached. 
Now I try to copy the Pdf file on a nextcloud instance. The connection is Ok, I managed to create the folders but my issue is : when I generate the pdf file, the corresponding invoice is deleted. 
Here is my code : 

from odoo import models, fields, api
import base64
import requests
import locale
import logging
from urllib.parse import quote
_logger = logging.getLogger(__name__)

class AccountMove(models.Model):
    _inherit = 'account.move'

    @api.model
    def envoyer_quittance_et_sauvegarder(self):
        # ID du modèle de facture à copier
        facture_modele_id = 16
        facture_modele = self.env['account.move'].browse(facture_modele_id)

        # Dupliquer et valider
        nouvelle_facture = facture_modele.copy()
        nouvelle_facture.action_post()
        # Envoi par mail
        template = self.env.ref('quittance.modele_email')
        template.send_mail(nouvelle_facture.id, force_send=True)

""" Code about construction of the Url and Nextcloud authentication """
        
        # Générer le PDF
        report = self.env['ir.actions.report']._get_report_from_name('account.report_invoice')
        pdf_content, _ = report._render_qweb_pdf(nouvelle_facture.id)
        
        # Envoyer le PDF sur Nextcloud
        response = requests.put(
            url_pdf,
            data=pdf_content,
            auth=(username, password),
            headers={'Content-Type': 'application/pdf'}
        )

        if response.status_code not in (200, 201, 204):
            _logger.warning(f" Erreur envoi PDF : {response.status_code} - {response.text}")
        else:
            _logger.info(f" Quittance enregistrée : {pdf_filename} dans {url_quittances}")

Is there another way for creating a pdf file?
