json-schema-valid

This rule validates a JSON Schema document against its declared metaschema.

If the document does not declare $schema, vacuum treats it as Draft 2020-12.

Why did this violation appear?

The schema uses a keyword, value shape or dialect feature that is not structurally valid for the selected JSON Schema dialect.

Bad example

{
  "type": 42
}

Good example

{
  "type": "object"
}

How do I fix this violation?

Fix the schema structure so it conforms to the declared dialect. Check $schema first if the document was written for an older dialect.
