"No plugins installed" warning message

Hello, I am experiencing difficulties that I'm unsure how to resolve. Basically, when I go to /admin/config/services/openapi I get the warning message about no plugins detected despite the JSON:API module being installed and working. I've included what I feel are helpful screenshots. Let me know if you need additional info.

Problem/Motivation

I have the latest version of D9 installed locally running in Docksal. I installed the JSON:API module, OpenAPI, OpenAPI UI, and Redoc for OpenAPI UI modules. Despite clearing the cache and referring to the README files included with each module, I still get:

  • the warning message (with unescaped HTML) at the top of the admin/config/services/openapi page about "No OpenApi generator plugins are currently available."
  • A 404 error when I go to the /admin/config/services/openapi/redoc/jsonapi
  • A JSON formatted message when I visit /openapi/jsonapi that reads {"message":"The \u0022openapi_generator\u0022 parameter was not converted for the path \u0022\/openapi\/{openapi_generator}\u0022 (route name: \u0022openapi.download\u0022)"}

Steps to reproduce

  1. Install D9 via composer
  2. Install the following modules:
    • JSON:API
    • HTTP Authentication
    • Serialization
    • Schemata
    • Schemata in JSON schema
    • OpenAPI
    • OpenAPI UI
    • Redoc for OpenAPI UI

Go to /admin/config/services/openapi (Warning message about no plugins being available).
Go to /openapi/jsonapi (JSON formatted message about openapi_generator parameter not converted for the path)
Go to /admin/config/services/openapi/redoc/jsonapi (404 error)

    Same issue.
    I have one d10 install in which it works and one in which it does not work.
    Couldn't figure out the difference :|

    The third screenshot clearly shows the problem. You need to install OpenAPI JSON:API → and/or OpenAPI for REST → , depending on which your are using.
    The first screenshot doesn't shown any of them present.

    As far as I've seen (just installed the whole shebang for the first time myself), neither of those modules are mentioned on the related module pages. Many cross-references from/to OpenAPI (UI) to Swagger UI for OpenAPI UI, ReDoc for OpenAPI UI and vice verse.

    These two modules are mentioned in the first and last section of the module's README.md though, but some extra exposure on the module page would be nice.
