Just a heads up, this weekend I tried starting a multiplatform project using kotlinx.serialization library and just couldn't figure out how to get it to serialize a response. I kept having the error I show below. I suspect it has something to do with the versions of the libraries I was using. I know that if you're using
Kotlin plugin version 1.3.70
you
MUST use
kotlinx.serialization version 0.20.0
because it's
NOT backwards compatible. Spent a whole day stuck, finally ended up reverting back to
Kotlin plugin 1.3.61
and
kotlinx.serialization 0.14.0
and it finally worked. Also used
ktor 1.3.1
. Just wondering if anybody has tried using the
kotlinx.serialization
library with
Kotlin 1.3.70
successfully?
Here's a GitHub gist:
