I have just become a victim to the dreaded UncaughtPromiseError on odoo 18. This occurs in the invoicing app when going to the supplier invoices. I receive my PEPPOL invoices here, so it is important for me that this works. 

All I can think of is an update I performed on my docker containers.

I tried going back to a backup, but that did not solve anything, neither did reinstalling odoo or trying another browser. I also tried recreating assets ... 

Anyone any other ideas ?
