adding colon inside string breaks gray-matter parsing

[Kartik]

In my md file, I have this at the beginning:

+++
authors = ["ABC"]
categories = ["cat"]
date = 2023-04-14T00:00:00Z
description = "Title: something about title"
draft = false
+++

... 

This results in error when I try to parse it like this:

const result = grayMatter(content, {
  delimiters: '+++',
  engines: { toml: toml.parse }
})

The error:

✖ Failed to compile template: filename.md
⚠ end of the stream or a document separator is expected at line 10, column 6:
    title = "Title: something about title"
                  ^

Is there a way to make the parser ignore the colon? Any help would be appreciated!

This worked:

const result = grayMatter(html, {
  delimiters: ['+++', '+++'],
  language: 'toml',
  engines: { toml: toml.parse.bind(toml) }
})
