Hi, I'm trying to implement a self hosted Odoo v18 enterprise server for managing the company's accounting.

I'm using a Windows server, I installed Odoo, download and configure the chilean localization, but after uploading the CAF, creating a quotation, confirm it, and prepare the invoice to be send to the SII, I'm getting the following error

Error de servidor de Odoo

RPC_ERROR

The above server error caused the following client error:
RPC_ERROR: Odoo Server Error
    RPC_ERROR
        at makeErrorFromResponse (http://10.0.1.203:8069/web/assets/83a26c2/web.assets_web.min.js:3131:163)
        at XMLHttpRequest.<anonymous> (http://10.0.1.203:8069/web/assets/83a26c2/web.assets_web.min.js:3136:13)

I understand the problem is in 

'rutSender': digital_signature_sudo.subject_serial_number[:-2]

but the digital certificate was uploaded correctly.

Any ideas how to fix it?
