Extension property: Function declaration must have a name Unresolved reference: get

I use extension function to extend retrofit2.Response object:

Snippet:

public class ErrorResponse {
    private int code;
    private String message;
    private Response response;
}

import okhttp3.MediaType
import okhttp3.Protocol
import okhttp3.Request
import okhttp3.ResponseBody
import retrofit2.Response

fun Response<*>.errorResponse(): ErrorResponse {
    val errorResponse = ErrorUtils.parseError(this)
    return errorResponse
}

And here use:

viewModelScope.launch(Dispatchers.Main) {
            val response: Response<*> = TransportService.getTraidersList()
            if (response.isSuccessful) {
                finishLoadData()
                val traders: List<Trader> = response.body() as List<Trader>
                traderListLiveData.postValue(traders)
            } else { 
                val errorResponse = response.errorResponse()
                val message = errorResponse.message // here use extension function
                messageLiveData.value = SingleEvent(message)
            }
}

Nice. It's work fine.

But I want to use extension properties. I try this:

val Response<*>.errorResponse: ErrorResponse {
   get() = ErrorUtils.parseError(this)
}

But I get compile error:

Function declaration must have a name Unresolved reference: get

You don't need brackets for properties. It may look like this:

val Response<*>.errorResponse: ErrorResponse
   get() = ErrorUtils.parseError(this)
