Bug Description

After updating beyond V25 to 26 (Or currently 29), the generated OpenAPI file is missing references, and types (components & schemas).

Reverting back to 25 from 26 (or 29) resolves the issue.

This makes it so that FE client generators are unable to create a proper client.

I was unable to find any changes in release 26 regarding this code, making it slightly confusing.

Diffing the files reveals that in v25, the components are referenced from otherplaces. In v26 they are inline.

Steps to Reproduce

1. Generate the spec in v25 and observe that the output is correct
2. Bump the version to v26 and observe that the output is broken

    "@strapi/plugin-cloud": "5.26.0",
    "@strapi/plugin-users-permissions": "5.26.0",
    "@strapi/strapi": "5.26.0",

3. Revert to v25 and observe it is correct again

    "@strapi/plugin-cloud": "5.25.0",
    "@strapi/plugin-users-permissions": "5.25.0",
    "@strapi/strapi": "5.25.0",

I don't believe there is anything specific to this codebase other than the version responsible for this.

Expected Behavior

A correctly generated file populated with types.

Additional information

I can provide the generated files if requested, but the project itself is WIP and the files are large.

Because it works when purely changing Strapi versions, i doubt its my code at fault. However i cannot conclude that it is not. Any pointers or help is greatly appreciated.

Running on Fedora 42 with PostgreSQL in Docker.

Confirmation Checklist

• I have checked the existing issues for duplicates.
• I agree to follow this project's Code of Conduct.

EDIT: The types are placed inline, but they are not defined as reusable components. As such, multiple tools will not pick it up and generate client types based on it (afaik), such as Hey API
