Short error message when validation fails

[iripiri]

Hello!

I was trying to use your project to validate JSON entities against fitting JSON schemas. Unfortunately, the validation fails with an error message which does not really help me: /: {"Balancing_MarketDo... did Not match any specified AnyOf schemas
I was expecting the validation to return successfully, since I checked the compatibilty of the JSON schema and entity before, using an online validator (https://www.jsonschemavalidator.net/) as well as the Python-Validator "Draft7Validator" from the jsonschema package for the same exact inputs.
Can you please help me with finding out what is going wrong?
My example is quite complex but I can post it or could try boiling it down to a simpler one, if neccessary.

Hi again,

since it was mentioned in the documentation that draft2019_9 is implemented here, I've made my test with Draft201909Validator in Python and used the same draft in the online validator as well. Both validations were successful, so the draft version was not an issue.
