Service from base class

[dshatz]

Is your feature request related to a problem? Please describe.
I am trying to make a Ktorit service that would extend a base service.
Example:

// common service for all build variants
interface BaseMessageService {
    @GET(...)
    suspend fun baseCall(): String
}

// extended implementation for e.g. a different client
interface CustomMessageService {
   @GET(...)
   suspend fun otherCall(): Double
}

The goal is to have a CustomService on which both baseCall and otherCall are available.
Ksp compiles but I am getting this runtime error when calling CustomMessageService.baseCall():

kotlin.UninitializedPropertyAccessException: lateinit property _converter has not been initialized
at _BaseMessageServiceImpl.get_converter
at _BaseMessageServiceImpl.baseCall
at _CustomMessageServiceImpl.baseCall

Creating CustomMessageService as usual ktorfit.create<CustomMessageService().

Describe the solution you'd like
The error makes sense - the generated CustomMessageServiceImpl extends BaseMessageService by _BaseMessageServiceImpl(). That new instance does not have the _converter because it is created by create which is not called here.
Not sure what the solution could be. I understand this usecase is not supported now? I may try to hack something.

Describe alternatives you've considered

• Copy paste base service methods to all extending services.
• Abandon the idea of extending and just have two separate services.

Hi, that was working once, but it looks like it got broken. I fixed it and it will work again with >= 2.0.0-beta2

Release 2.0.0 says this was fixes... so I guess the issue should be closed?

@sschuberth You are right, thanks

Maybe a good idea to document that this is supported.
