Description

In the configuration.py file after generating a python client, it says:

# Disable client side validation
self.client_side_validation = True

This makes it seem like client side validation is disabled by default. But it's not.

The comment should be # set to False to disable client side validation, or just # Enable client side validation

openapi-generator version

openapi-generator-cli 5.0.0-SNAPSHOT
