Foremost, thanks for your work on this importer. I use it since a couple of years and it never failed me.

I recently switched my computer and had to reinstall beancount with the DKB-Importer. With the new install, I switched to beancount 3. I changed the configuration to use pyproject.toml. The use of beancount-dkb-ec work on my first try, but extracting my credit card information fails with an error.

I created a minimal example by deleting all transactions, except one (see below).
