/**
 * Formats a {@link VariableResult} for an {@link ApiResponse} using a {@link matcher}.
 * If the data is not an object or an array, i.e. a primitive value, an object with the matched type
 * is returned. The type is defined as the `_type` property.
 *
 * @remarks
 * If `undefined` or `null` is returned from the {@link matcher}, `console.error` is used to print an error
 * detailing that no response type could be resolved, and the response data is returned without a type.
