Problems portfolio YAMLException

[steep kernel]

From the looks of the error, seems something with wrong with tag:.
Is your portfolio open source somewhere, I can take a peak around the code.

I haven't put it on GitHub yet

Here is the code in config.ts :

import { defineCollection, z } from 'astro:content';

export const collections = {
work: defineCollection({
schema: z.object({
title: z.string(),
description: z.string(),
publishDate: z.coerce.date(),
tags: z.array(z.string()),
img: z.string(),
img_alt: z.string().optional(),
}),
}),
};

Typically this is caused by a syntax error in a Markdown frontmatter

Often with multi-lines attributes, because the syntax can be a bit finicky in YAML (the language used in Markdown frontmatter)

the problem is that everything was working normally, I haven't changed anything since and now I can't launch it

Could you perhaps have ran a formatter or something similar on your Markdown files?

I've been using the Prettier and Eslint extensions since the beginning.
