The character : should be encoded https://perishablepress.com/stop-using-unsafe-characters-in-urls/

forget to mention, of course it was encoded, just pasted here decoded
Anyway testing via domain/v1/user/a%3Ab/subscriptions and It gives same result (Resource not found)

i will look at it

some hint, when using regular vertx router , then all is fine

val router = routerFactory.router
            with(router) {
                get("/v1/user/:UUID/subscriptions")

only when switching to OpenAPI3RouterFactory, problem appears

Additional info. yml defintion says about this parameter as

      in: path
      required: true
      schema:
        type: string

Please check this PR: #872

thank you. Looks promising.

I can see it will be released with 3.6.0 , right?
So, what is the schedule for it, estimation of deploy/release date?

is there chance for inter release like 3.5.2 ?

after fix, I will be able to use : or only encoded %3A or both ?

I don't know when the next version will be release. I think that : won't work because it's a reserved character that should be escaped

Just watch this regex https://github.com/vert-x3/vertx-web/pull/872/files#diff-ef77bbac586ab216b4fc91092e1085fcR91

In the spec (https://tools.ietf.org/html/rfc3986#section-3.3) we found out that ':' is technically valid in the path segment of a url - so we do not need encode

Please look at field allowReserved (that we don't support, we assert that is always false) https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.1.md#fixed-fields-10

I've created a new PR that refactor the path generation: #884
