[2.0.6] Pattern Validation fails with Drupal 11.2

Problem/Motivation

Drupal 11.2 upgrades to justinrainbow/json-schema to 6.3 which improves the schema validations. This leads to validations errors based on wrong ref imports.

Steps to reproduce

Run tests.

  [props.properties.enum_integer.enum] There must be a min  
  imum of 1 items in the array, 0 found                     

Proposed resolution

Fix ref imports.
