改造响应中的Proguard中断类变量

如何解决改造响应中的Proguard中断类变量

我有WhoIAmResponse和ProfileResponse，但如果我尝试从ProfileResponse获得任何价值，我会得到kotlin NPE。我在Logcat中进行调试的尝试表明，配置文件响应已被r8混淆（但在proguard-rules中对此规则有规定）

Timber.i(whoIAmResponseBody.result.toString())
Timber.i(whoIAmResponseBody.result.profile.toString())

if (whoIAmResponseBody.result.profile == null)
  Timber.e("profile NULL")
else {
   Timber.i("profile NOT null")
   Timber.e(whoIAmResponseBody.result.profile?.name
         ?: "username NULL") //here i get NPE (and anywhere below if i try to access profile values)
 }

data class WhoIAmResponse(
    @Serializedname("id")
    val userId: Long? = null,@Serializedname("suid")
    val suId: Long? = null,@Serializedname("userid")
    val userProfileId: Long? = null,@Serializedname("profile")
    val profile: ProfileResponse? = null
) : BaseResponse()


data class ProfileResponse(
    @Serializedname("id") val id: Long,@Serializedname("username") val username: String? = null
)
