Error: Cannot start the application. S2OError: Could not resolve reference #/definitions/uuidFromString

Hi, I have an lb3 project with cassandra as the db. I've followed the steps here: https://github.com/loopbackio/loopback-next/tree/master/examples/lb3-application#tutorial to mount my lb3 app on lb4, but I'm getting the error:

Swagger: skipping unknown type "uuidFromString".
Swagger: skipping unknown type "uuidFromString".
Cannot start the application. S2OError: Could not resolve reference #/definitions/uuidFromString

      consumes: [Array],
      produces: [Array],
      definitions: [Object]
    },
   .
   .
   .

Seems for models with uuid fields are not mapped correctly to swagger definitions.
Here is the SQL used in my migrations file:

CREATE TABLE IF NOT EXISTS "Creature" ("name" VARCHAR,
      "username" VARCHAR,
      "email" VARCHAR,
      "password" VARCHAR,
      "realm" VARCHAR,
      "emailVerified" BOOLEAN,
      "verificationToken" VARCHAR,
      "id" UUID,
      PRIMARY KEY("email", "id"));`

Please advise if there are other solutions other than migrating my app models all in one go, thank you
