Scanner FieldAnnotationsScanner was not configured

See original GitHub issue

Looks like in the new version of Kotless a bug has been introduced in relation with the reflection capabilities.

With a simple code like:

import io.kotless.dsl.lang.http.Get

@Get("/hello")
fun sayHello() = "Say Hello!"

When the endpoint is hit the following exception is thrown:

Going back to version 0.1.3 solves the problem (using diverse versions of Kotlin: 1.3.61 and 1.3.72)

Note: The problem is reproducible in local

Yep, actual culprit is update to reflections:0.9.12 – https://github.com/ronmamo/reflections/issues/273 . For now I’ll revert this update, but will consider move to another library
