Send an email when Sales invoice is paid

[jordi_marti_gomez]

Hello, i know there are several topic regarding Notifications and how they are built to send an email to the customer when a Sales invoice is paid, but im not able to make it work and i think that i’ve done it correctly.

So, the solution that im trying to find is how to send an email to the customer who paid the Sales Invoice, this is my ERPNext setup:

ERPNext: v15.53.2 (version-15)
Frappe Framework: v15.56.1 (version-15)
Payments: v0.0.1 (develop)
Webshop: v0.0.1 (develop)

1. I’ve set up a new Notification for Sales Invoice, Looking for **Value Change ** in status field:
   

   

2. Condition i’ve set it up to only be triggered when the status is: Paid with the following code:
   

3. I’ve set up the recipients to be the owner and the Contact email of the customer as shown:

I can’t make it work in any of the status, it just doesn’t run,

I’ve done another change for testing purpouses without the condition,
And the only thing that i’ve got is an Error Log saying: The document can’t be notified when the status is Cancelled.

So, why this is not triggering an automatic email to the user?

Thank you for your help in advice
