I am using retrofit to make a post api call, I am getting the following error while trying to hit the endpoint.
Caused by: rx.exceptions.OnErrorNotImple
It seems that Retrofit rel.1.9 is prone by the issue (https://github.com/square/retrofit/issues/854).
In the meantime, consider downgrading to rel.1.6 until current release will be fixed. It is verified that rel.1.6 is free of this particular bug.
