Fix #15489

Summary

Previously we didn't support converting Mixed type to JSON schema, but I did some more digging and it looks like we can represent mixed types properly in JSON schema. This PR adds toJSONSchema() to Mixed types, and also improves the "Converting unsupported SchemaType to JSON Schema" to include the schematype path.

Examples

Pull Request Overview

This PR enables conversion of Mixed schema types to JSON Schema and enhances the error message for unsupported schema types by including the path.

  • Implements toJSONSchema() on SchemaMixed to return an open schema ({}).
  • Updates the generic toJSONSchema() error to include this.path.
  • Adjusts existing tests to validate Mixed type support and removes the old unsupported-Mixed error test.

Reviewed Changes

Copilot reviewed 3 out of 3 changed files in this pull request and generated 2 comments.

File Description
test/schema.test.js Added a mixed field (any) to the schema and updated assertions
lib/schemaType.js Enhanced unsupported-type error message to include the schema path
lib/schema/mixed.js Added toJSONSchema() stub on SchemaMixed returning {}
Comments suppressed due to low confidence (2)

test/schema.test.js:3887

  • The removal of the Mixed-type error test means there’s no remaining test for the enhanced error message with path context. Consider adding a test for an unsupported schema type (e.g., a custom type) to confirm the thrown error includes the path.
    });

lib/schemaType.js:1783

  • [nitpick] The new error message includes path information but lacks JSDoc comments on this override. Consider adding or updating a JSDoc block above SchemaType.prototype.toJSONSchema to document the new path context in the error.
  throw new Error(`Converting unsupported SchemaType to JSON Schema: ${this.instance} at path "${this.path}"`);

LGTM.

PS: there seems to be a sorting issue with the encryption tests.
