Hello everybody,
* postgres 16 → 18
* python 3.12 → 3.14
I re-created a new VENV. As system-wide pip install is no longer supported, I installed python libraries by using apt.
Tryton is working, but when I try to import a CAMT052 bank statement, I get this error message:
Fault: conversion from NoneType to Decimal is not supported
My guess is that I’m still missing a python library, but could not find it by comparing install lists. Any hint will be appreciated.

The series 7.0 does not support Python 3.14, the highest version supported is Python 3.12.

Python 3.14 is supported by Tryton 8.0 series, so the saffer path is to upgrade also your trytond version to 8.0 series.

My guess is that I’m still missing a python library, but could not find it by comparing install lists.
But it is probably not a dependency issue but it is hard to say without the full traceback.
Meanwhile I succeeded in updating to v8.0. But the problem remains:

This is the message appearing: TypeError: conversion from NoneType to Decimal is not supported.
Still not 100% sure if I’m missing a module, so below is my module list.
EG
´´´
appdirs 1.4.4
I tried to check it at demo8.0.tryton.org. But there, I cannot select any statement format; without such, the import does not proceed.

The error tells me there is something weird in your statement file. It seems the module cannot find any amount related to a specific entry.
It would be nice if you could isolate that particular entry, anonymize it and post the details so we can try to reproduce it.
Also what about the same statement, but then in camt053 format? Does that import correctly?
Hm. WITHOUT having loaded a statement xml, it looks like this in my local v8.0:
and like that at the demo:
None of views changes when an xml is uploaded.
NB: It’s just an ordinary CAMT52 statement from a German Genossenschaftsbank. I think, Tryton should be able to handle it - and did so in the past.
