Handling two different Retrofit responses for success and error in Kotlin

I'm building an android app in Kotlin, and the response comes in two different structures for success and error. My question is, can I combine those two responses together and create a data class, or should I create a sealed class for that? Success response:

{
    "access_token": "xxxxxxxxxxxxxxxxxxxx",
    "token_type": "bearer"
}

Error response:

{
    "detail": [
        {
            "loc": [
                "body"
            ],
            "msg": "Invalid credentials",
            "type": "invalid-credentials"
        }
    ]
}

So can I write it all like this in a single data class or use a sealed class?

data class Auth (
   val access_token: String,
   val token_type: String,
   val details: Details
)

Yes try combining all the data into a single data class. Just make all the variables optional.

data class Auth (
   val access_token: String?,
   val token_type: String?,
   val detail: List<Detail>?
)

Edit: On how to access the nested data. Pretty Simple.

data class Detail ( 
  val loc: List<String>,
  val msg: String,
  val type: String
)

Then when an error occurs you access the data with something like val msg = auth.detail?.msg
