Recently I switched to MoshiConverterFactory from GSONConverterFactory. Every thing s working fine except the one call. Like other API calls here also I am using @Body annotation but I am getting this error java.lang.IllegalArgumentException: Unable to create @Body converter for class

my request class :

data class DemoRequest(
val emailId: String? = null,
val demoData: List<DemoDomain?>? = null,
val userName: String? = null

)

One more thing here to mention that with GSONConverterFactory it is working fine but as I switched to MoshiConverterFactory it is throwing error.

retrofitVersion = '2.3.0'

service interface:

@POST("call/api")
fun sendToServer(@Body request: DemoRequest):retrofit2.Call<RemoteResponse>

val retrofit = Retrofit.Builder()
            .baseUrl(BASE_URL)
            .client(okHttpClient)
            .addConverterFactory(MoshiConverterFactory.create())
            .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
            .build()

UPDATE------------- I was sending Date object in request so I need to use custom adapter and it is working fine now

Did you remember to change to MoshiConverterFactory when you build Retrofit?

Retrofit.Builder().baseUrl(...).addConverterFactory(MoshiConverterFactory.create()).build()

Also, the latest version of Retrofit is 2.5.0 so you could try upgrading and make sure your converter is also the same version.
