PointerToNowhere error when validating CRDs #216

I have tried creating a schema and validating yaml file structures based on their datatype and I have been constantly getting the same error no matter how I try to resolve it.

The source code where I'm getting this error is here: Openapi_validation

Steps to Reproduce

• Run pip install pyyaml openapi_schema_validator
• Run python validate_crd.py valid_crd.yaml

Error Message:

❌ Validation Error: PointerToNowhere: '/components/schemas/CustomAttribute' does not exist within {'oneOf': [{'type': 'string', 'minLength': 0, 'maxLength': 100, 'default': '', 'pattern': '.*', 'description': 'A string value.'}, {'type': 'integer', 'minimum': 0, 'maximum': 100, 'default': 0, 'description': 'An integer value.'}, {'type': 'boolean', 'default': False, 'enum': [True, False], 'description': 'A boolean value.'}, {'type': 'array', 'items': {'oneOf': [{'type': 'string'}, {'type': 'integer'}, {'type': 'boolean'}, {'$ref': '#/components/schemas/CustomAttribute'}]}, 'default': [], 'description': 'An array of values.'}, {'type': 'object', 'properties': {'default': {'type': 'object'}, 'description': {'type': 'string'}, 'properties': {'type': 'object', 'additionalProperties': {'$ref': '#/components/schemas/CustomAttribute'}}}, 'required': ['default', 'description', 'properties']}]}

It would really help if there is any fix for this
