Official json5.org example results in 'InvalidIdentifier' error

[Synthasmagoria]

Zig version 0.14.1
OS: Ubuntu 24.04 LTS
Hi, tried out your library for a project and dropped in the json5 example on json5.org:

const json5 = @import("json5.zig");
const std = @import("std");

const JSON5 =
\\{
\\  // comments
\\  unquoted: 'and you can quote me on that',
\\  singleQuotes: 'I can use "double quotes" here',
\\  lineBreaks: "Look, Mom! \
\\No \\n's!",
\\  hexadecimal: 0xdecaf,
\\  leadingDecimalPoint: .8675309, andTrailing: 8675309.,
\\  positiveSign: +1,
\\  trailingComma: 'in objects', andIn: ['arrays',],
\\  "backwardsCompatible": "with JSON",
\\}
;

pub fn main() !void {
    const a = std.heap.page_allocator;
    var parser = json5.Parser.init(a, false);
    defer parser.deinit();
    var tree = try parser.parse(JSON5);
    defer tree.deinit();
}

And got the following error

error: InvalidIdentifier

I don't know much about parsing myself.
Hopefully the code is good enough for the issue to be identified.
