this doesn't appear to work as intended. @aeschli

take the following example:

{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "$id": "https://example.com/schemas/user-profile.schema.json",
  "unevaluatedProperties": false,
  "type": "object",
  "required": ["name"],
  "properties": {
    "name": { "type": "string" }
  }
}

---

Failing Instance

# yaml-language-server: $schema=c:\users\fieljere\repos\api-specs\untitled-1.json

true

The error output gives a random message about user-profile. Is the intention to reference the schema $id?

[{
"resource": "Untitled-2",
"owner": "generated_diagnostic_collection_name#1",
"severity": 8,
"message": "Incorrect type. Expected "user-profile".",
"source": "yaml-schema: file:///c%3A/users/fieljere/repos/api-specs/untitled-1.json",
"startLineNumber": 3,
"startColumn": 1,
"endLineNumber": 3,
"endColumn": 5,
"origin": "extHost1"
}]

another example:

# yaml-language-server: $schema=c:\users\fieljere\repos\api-specs\untitled-1.json

{
  "jeremy": 1
}

No error output This should throw an error for unevaluatedProperties

@jeremyfiel Please create an issue if you can reproduce that in pure JSON
YAML is an extension, I don't know if they have adopted already.
