How to declare Array of complex object in the mdx frontmatter

[ezzle]

Hi

I Have the following schema

export const frameSchema = z
    .object({
        frametype: z.literal('frame').optional().default('frame'),
        name: z.string(),
        type: z.string().optional(),
        supertype: z.array(z.string()).optional(),
        own_slot_value: z.array(z.object({
            slot_reference: z.string(),
            value: z.array(z.object({
                value_type: z.string(),
                value_content: z.string()
            }))
        })).optional(),
        superclass: z.array(z.string()).optional(),
        template_slot: z.array(z.string()).optional(),
        template_facet_value: z.array(z.object({
            slot_reference: z.string(),
            facet_reference: z.string(),
            value: z.array(z.object({
                value_type: z.string(),
                value_content: z.string()
            }))
        })).optional()
    })
    .strict();

And The following frontmatter declaration :

---
frametype: "class"
name: ":THING"
type: "STANDARD-CLASS"
supertype: ["CLASS", ":META-CLASS", ":SYSTEM-CLASS", ":THING"]
own_slot_value: [{slot_reference:":ROLE", value:[{value_type:"string", value_content: "Abstract"}]}]
---

And I am getting the following error
InvalidContentEntryFrontmatterError: **essential → en/class/thing.mdx** frontmatter does not match collection schema.

Please help.

own_slot_value is the cause. How to declare an array of objects containing array of objects ?

Thank you in advance

Hi @ezzle! Couple things here:

1. Looks like your schema says that frametype must be frame, but in the frontmatter example it’s set to class, so that might be an issue.

2. I think you maybe need to make sure there’s a space after each : in the object declarations of own_slot_value:

   - own_slot_value: [{slot_reference:":ROLE", value:[{value_type:"string", value_content: "Abstract"}]}]
   + own_slot_value: [{slot_reference: ":ROLE", value: [{value_type: "string", value_content: "Abstract"}]}]

By the way, we have a friendly Discord server if you’re looking for support in the future. We’d be happy to have you there! https://astro.build/chat

Hi delucis.
Worked fine.
By the way, I provided just a snippet of the schema. 'class' is an extension ...
Thank you.
