Are you sending Accept: application/json in your request to the server?

Right now, the only supported ContentNegotiation strategy when sending, is the client’s Accept header.

yep here is a rest-client i'm using

if i put map there will be no problem, it will be serialized to json but if data class i still get null

You’re registering multiple handlers for gson. The gson builder is already registering a GsonConverter to ContentType.Application.Json, but you’re also registering a different converter via register(Json, GsonConverter()).

the same error ( everytime it's just return null except data class

[Бежан Александр]

also if i replace to User().toString() it will return toString somth wrong with gson conversion

may be for future i have found a solution, i just replaced gson to jackson and everything started. But for gson still no answer why it is so

I personally haven’t used gson to suggest anything in addition 😕

I had the same problem with Gson and a Json file that contain an array of Objects... in the end I had to create a custom serializer
