Subject: Aw: Re: RecursionError when try to check bindings (ubuntu 22.04 /
 Python3.10)

Hi,

seems like this fixes it (at least i get over the faulty point see now the DTEX lines):

pip3 install jsonschema==4.17.0

seems my previous version was 4.6.0

Requirement already satisfied: jsonschema in /home/frank/.local/lib/python3.10/site-packages (4.6.0)

first tried upgrade of this, but this results in 4.19 which is not compatible with dtschema

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
dtschema 2023.7 requires jsonschema<4.18,>=4.1.2, but you have jsonschema 4.19.0 which is incompatible.

so i set the last version told to be compatible

regards Frank
