JsonType is undefined, global object in block content annotations

[JanneHelewaut]

Hello!
I’m editing the annotations in the block content to support external links and other custom objects in the new V3.
Since I’m using GraphQL, I can’t have any inline objects and all objects need to be defined globally. So I created a type externalLink as:

export default {
  name: 'externalLink',
  title: 'External Link',
  type: 'object',
  liveEdit: false, 
  fields: [
    {
      title: 'URL',
      name: 'href',
      type: 'url',
    },
  ]
}

I added this type to the schema. but when I want to place it in the annotations of my block Content, I get the following error:

Error: Could not resolve jsonType of undefined. No parent type found

And this is my BlockEditor code:

export default {
  title: 'Block Editor',
  name: 'blockEditor',
  type: 'array',
  of: [
    {
      title: 'Block',
      type: 'block',
      styles: [
        {title: 'Normal', value: 'normal'},
        {title: 'H2', value: 'h2'},
        {title: 'H3', value: 'h3'},
        {title: 'Quote', value: 'blockquote'},
      ],
      lists: [{title: 'Bullet', value: 'bullet'}],
      marks: {
        decorators: [
          {title: 'Strong', value: 'strong'},
          {title: 'Emphasis', value: 'em'},
        ],
        annotations: [
          {
            type: 'externalLink'
          }
        ],
      },
    },
    {
      type: 'image',
      name: 'image',
      options: {
        hotspot: true,
      }
    },
    {
      name: 'line',
      title: 'Line',
      type: 'line',
    },
  ],
}

This example shows me that it is possible (in V2), so my question is, what am I doing wrong here?
[I’m using version 3.0.1-dev-preview.0]

@JanneHelewaut - have you defined the externalLink type in the schema before it is used here?

The shorthand {type: 'externalLink'} would require that type to be defined elsewhere before it is used like that here.

Just to confirm this first.

[JanneHelewaut]

I did, if I use the externalLink outside of annotations it works fine. e.g. if I put it underneath the image and line, it is shown in the block content without any issues.

[JanneHelewaut]

I created a git repo with a really basic blockeditor that shows the issue really well.

After a lot of testing, we figured out the issue was in the order of the schemaTypes. When we put the externalLink before the BlockContent in the schemaTypes, it works.

We just ran into this issue earlier today, surely this isn't intentional behavior? The order of the schema types should not affect inter-referencing between schema types?
