Code sample

const data = {
  "@id": "test"
}

JSONPath({json: data, path: "$['@id']", wrap: false});

Console error or logs

TypeError: Unknown value type

Expected behavior

I should be able to select attributes at the root of an object that start with special characters such as "@id"

Expected result

In the example above I expect to get "test" as a result

Environment (IMPORTANT)

"jsonpath-plus": "^10.4.0",

Extra Info

This works when accessing a nested object (For example, "$.foo['@id']")
