Test-App doesn't work

[rdmueller]

The swagger files and swagger-ui now look great and I love that I can switch between XML and JSON.

But as soon as I try to use the test-app (with gradle 3.0 or grails 3.2.6), I only get exceptions.

Example:
https://localhost:8080/artist/index
should return a list of all known artists or an empty list []
Instead it returns a 500 with a stacktrace on the console which look like this:

ERROR org.grails.web.errors.GrailsExceptionResolver - IllegalArgumentException occurred when processing request: [GET] /artist/index
id to load is required for loading. Stacktrace follows:

unfortunately, I am not familiar (yet) with this kind of controller shortcut which is used in the example... so I can't easily find the problem. How has the test app been created?

[dilipkrish]

let me take a look... I suspect it was created through the grails command line

[dilipkrish]

Seems like a case of operation success but patient is out :) Trying to reproduce it on a new project

[rdmueller]

that's what I currently try too!

[rdmueller]

I get the feeling that this could be a problem (bug?) with grails rest scaffolding...

[dilipkrish]

I think I figured it out.. its rendering the wrong paths

[dilipkrish]

For e.g.

create is POST /book {...} and not POST /book/create {..}
