withContext-ArrayIndexOutOfBoundsException

Question

在Android应用中，我想在后台线程中执行网络操作。 因此，我为此使用Kotlin协程withContext(Dispatchers.IO)：

摘要：

@GET("trader/{trader_operation}")
    Deferred<Response<Void>> executeTraderOperation(@Path("trader_operation") String traderOperation,
                                                    @Query("base") String base,
                                                    @Query("quote") String quote,
                                                    @Query("sender") String sender,


import kotlinx.coroutines.*
import retrofit2.Response
import java.util.*
class TransportService {
        companion object {
            private val SERVICE_UNAVAILABLE_CODE = 503

            private val TAG = TransportService::class.java.name@Query("key") String key);

     suspend fun executeTraderOperation(traderOperation: Trader.Operation, base: String, quote: String): NetworkResponse {
                val traderMonitorRestClient = RestClientFactory.createRestClient(TraderMonitorRestClient::class.java)
                val sender = BuildConfig.APPLICATION_ID + "_" + BuildConfig.VERSION_NAME
                val key = DateUtil.getDateAsString(Date(), "mmHHddMMyyyy")
                val operrationDeferred: Deferred<Response<Void>> = traderMonitorRestClient.executeTraderOperation(traderOperation.toString().toLowerCase(), base.trim(), quote.trim(), sender, key)
                return executeOperation(operrationDeferred)
            }

            private suspend fun executeOperation(operation: Deferred<Response<*>>): NetworkResponse = withContext(Dispatchers.IO) {
                val networkResponse = NetworkResponse()
                try {
                    val response = operation.await()
                    networkResponse.isSuccess = response.isSuccessful
                    if (response.isSuccessful) {
                        networkResponse.successResponse = response
                    } else {
                        val errorResponse = ErrorUtils.parseError(response)
                        networkResponse.errorResponse = errorResponse
                    }
                    networkResponse
                } catch (e: Throwable) {
                    val errorResponse = ErrorResponse()
                    errorResponse.setCode(SERVICE_UNAVAILABLE_CODE)
                    errorResponse.setMessage("Service unavailable")
                    networkResponse.errorResponse = errorResponse
                    networkResponse
                }
            }
    }
    }

但是在此行中出现运行时错误：

val operrationDeferred: Deferred<Response<Void>> = traderMonitorRestClient.executeTraderOperation(traderOperation.toString().toLowerCase(), base.trim(), quote.trim(), sender, key)

此处错误：
