As I understand it - The $schema keyword is used to point to a JSON Schema that describes the shape of a valid JSON schema itself.

The most recent version of the JSON Schema spec is 2020-12 https://json-schema.org/specification.html

If we try use a schema with

  "$schema": "https://json-schema.org/draft/2020-12/schema",

RSJF will show a validation error:

no schema with key or ref "https://json-schema.org/draft/2020-12/schema"

The most recent version of JSON schema should be supported.

Navigate to: https://rjsf-team.github.io/react-jsonschema-form/
Paste "$schema": "https://json-schema.org/draft/2020-12/schema", into the top level of the schema
Submit the form
Observe the validation error

Sandbox

No response

Research direction: Examine the source code to find where supported JSON Schema drafts are defined (likely in a constants file or validation setup). Check if the underlying validator (ajv) supports the 2020-12 draft; if not, upgrade the validator. Add the 2020-12 schema URL to the list. Run existing tests and add a simple test for the new draft. Update documentation if necessary. See issue comments for any additional hints.
