Fail State call twice and make error

[rzgonz]

i want changes error message Fail state whit this

suspend {
            userUseCase.getUserProfile()
        }.execute(Dispatchers.IO) {
            if(it is Fail){
                val errorMessage = handleErrorBE(it.error)
                copy(userProfileDto = Fail(errorMessage))
            }else{
                copy(userProfileDto = it)
            }

but this make an error

java.lang.IllegalArgumentException: Impure reducer set on Repository! userProfileDto changed from Fail(error=java.lang.Throwable: Internal Server Error, value=null) to Fail(error=java.lang.Throwable: HTTP 500 , value=null). Ensure that your state properties properly implement hashCode.

this error cause Fail state call twice when i see log output, then the last output message null

when i implement like this

            setState {
                copy(userProfileDto = Loading())
            }
            try {
                val response = userUseCase.getUserProfile()
                setState {
                    copy(userProfileDto = Success(response))
                }
            } catch (e: Exception) {
                val errorMessage = handleErrorBE(e)
                setState {
                    copy(userProfileDto = Fail(errorMessage))
                }
            }
        }

this works perfectly. when I use a function from Mavericks, it makes an error.

It's impossible to help here without more context. Can you reproduce this in another project? What does handleErrorBE(it.error) do? Looking at the error message, something you're doing is causing errorMessage to change from java.lang.Throwable: Internal Server Error to java.lang.Throwable: HTTP 500 which makes the Mavericks impure check to correctly trigger.

@gpeal handleErrorBe is a function for Parce my api error message

fun handleErrorBE(error: Throwable): Throwable {
    val message = safeLaunchWithResult(error.message.orEmpty()) {
        val response = (error as? HttpException)?.response()?.errorBody()?.string()
        val gson = Gson().fromJson(response, ErrorResponse::class.java)
        gson.apiDisplayMessage.orEmpty()
    }
    return Throwable(message)
}

inline fun <reified T> safeLaunchWithResult(default: T, block: () -> T): T = try {
    block()
} catch (e: Exception) {
    e.printStackTrace()
    default
}

and return an error message to Fail Message for the state pemilihEditDtoAsyn

I use retrofit 2.9.0 for network connection and implement Kotlin delegation and jetpack compose

i try at same project with this code

 val requestBody: RequestBody = builder.build()
logD<PemilihEditViewModel>("state begin")
            suspend {
                pemilihUseCase.updatePemilih(state.pemilihDetailDto?.id.toString(), requestBody)
            }.execute(Dispatchers.IO) {
                logD<PemilihEditViewModel>("state $it")
                copy(pemilihEditDtoAsyn = it)
            }

and the output is

and this my repository

 @PUT("pemilih/{id}")
    suspen fun updatePemilih(
        @Path("id") id: String,
        @Body file: RequestBody
    ): BaseResponse<PemilihAddResponse>
