Current Behavior

When using the new unstable_defineSchema from tina-graphql-gateway-cli it will not launch the dev server.

Expected Behavior

It should start the graphql server.

and this Schema.ts


import { defineSchema, unstable_defineSchema } from "tina-graphql-gateway-cli";

export default unstable_defineSchema({
  collections: [
    {
      label: "Docs",
      name: "docs",
      path: "docs",
      templates:[
        {
          name: 'doc',
          label: 'doc',
          fields: [
            {
              type: 'text',
              name: "title",
              label: "Title of page",
            },
          ]
        }
        ]
    },
    {
      label: "Blog Posts",
      name: "posts",
      path: "content/posts",
      templates: [
        {
          label: "Article",
          name: "article",
          fields: [
            {
              type: "text",
              label: "Title",
              name: "title",
            },
          ],
        },
      ],
    },
  ],
});

Note that this works with defineSchema but not with unstable_defineSchema. This error happens when the dev servers starts.
