Swagger UI configuration problem

[pezra]

I'm getting a 404 when I try to access the swagger UI. The 404 response comes from the swaggerUI routing because it's body is different from the 404s from my application. The openapi JSON generation is working correctly. My config is

     routing {
        route("/account/v2/api.json") {
            openApiSpec()
        }
        route("/account/v2/swagger") {
            swaggerUI("/account/v2/api.json")
        }    
    }

when I visit accounts/v2/swagger in my browser, I get a 404 with the body index.html could not be found. Same thing using cUrl

curl http://localhost:8081/account/v2/swagger -vL
> GET /account/v2/swagger HTTP/1.1
...
< HTTP/1.1 302 Found
< Location: /account/v2/swagger/index.html
...
> GET /account/v2/swagger/index.html HTTP/1.1
...
< HTTP/1.1 404 Not Found
...
index.html could not be found%

Any pointers on how to correct this?

Hi @pezra

strange. Your routes look fine and I'm not sure what else could affect this.

I did a quick test with this application:

fun main() {
    embeddedServer(Netty, port = 8081, host = "localhost", module = Application::myModule).start(wait = true)
}

private fun Application.myModule() {
    install(SwaggerUI)
    routing {
        route("/account/v2/api.json") {
            openApiSpec()
        }
        route("/account/v2/swagger") {
            swaggerUI("/account/v2/api.json")
        }
        get("test", {
            description = "A test route"
        }) {
            call.respondText("test response")
        }
    }
}

This works in my browser (both with and without /index.html) and got this output from curl:

~ » curl http://localhost:8081/account/v2/swagger -vL

> GET /account/v2/swagger HTTP/1.1
...
< HTTP/1.1 302 Found
< Location: /account/v2/swagger/index.html
...
* Issue another request to this URL: 'http://localhost:8081/account/v2/swagger/index.html'
...
> GET /account/v2/swagger/index.html HTTP/1.1
...
< HTTP/1.1 200 OK
< Content-Length: 734
< Content-Type: text/html
...

Does only the redirect result in a 404 or also when you access the /index.html directly?
Do you have a rootPath or anything else configured for ktor that could influence that?
