Issue with json objects

[sqbl]

It appears that a fresh install of python and dependencies for the api is giving a jsonschema that errors.
Error message:
"
...
File "/home/sb/anaconda3/envs/Boost/lib/python3.8/site-packages/connexion/json_schema.py", line 65, in validate_type
yield ValidationError(_utils.types_msg(instance, types))
AttributeError: module 'jsonschema._utils' has no attribute 'types_msg'
"

Solved by reading the manual ;-)
A "normal" pip install -r requirements.txt led to a version of jsonschema that is incompatible.
Use pip install -r requirement-freeze.txt instead
