JWT Auth in Vert.x 5

Question

I am using Vert.x 5.0.0 SNAPSHOT in a new project. We have code in previous Vert.x v4.4.3 projects to add JWT authorization to a router built from an OpenAPI spec:

RouterBuilder
   .create(this.vertx, OPENAPI_URL)
   .compose(routerBuilder -> {

      // AUTHENTICATION & AUTHORIZATION
      routerBuilder.securityHandler("bearerAuth", Config.jwt().getAuthHandler());

      //...

But in 5.0.0 there's only a security method that receives a String and returns a Security object. That security object then accepts a handler and returns a RouterBuilder again:

router
   .route("/v1/*")
   .subRouter(routerBuilder
      .security("bearerAuth")
      .httpHandler(Config.jwt().getAuthHandler())
      .createRouter()
   );

But when I run it, it throws an exception on the .security("bearerAuth") line:

java.lang.NullPointerException: 'securityScheme' cannot be null

I can't find documentation or examples on how to do this. Any help will be appreciated!

Solved. The OpenAPI spec needs to have the "bearerAuth" security scheme, and we were loading multiple files and it wasn't on every one of them.
