只能从同一个库组内调用成功(引用groupId=androidx.work from groupId=My Composable)

我一直在try 使用工作管理器和下载图像使用 retrofit ，并面临这个问题.

问题出在这段代码中

Result.Success( // This is creating problem
                    workDataOf(
                        WorkerConstants.IMAGE_URI to file.toUri().toString()
                    )
                )

这是完整的功能代码.

    override suspend fun doWork(): Result {
        startForegroundService()
        delay(5000L)

        val response = FileAPI.instance.downloadImage()
        response.body()?.let { body ->

                val file = File(context.cacheDir, "image.jpg")

                outputStream.use { stream ->

                )
            }
        }
        if (!response.isSuccessful){
            if (response.code().toString().startsWith("5")){ 
                return Result.retry()
            }
            return Result.failure(
                workDataOf(
                    WorkerConstants.ERROR_MSG to "Network error"
                )
            )
        }
        return Result.failure(
            workDataOf(
                WorkerConstants.ERROR_MSG to "Unknown error"
            )
        )
    }

    private suspend fun startForegroundService() {
        setForeground(
            ForegroundInfo(
                Random.nextInt(),
                NotificationCompat.Builder(context, WorkerConstants.channelId)
                    .setSmallIcon(R.drawable.skull)
                    .setContentText("Downloading...")
                    .setContentTitle("Download in progress")
                    .build()
            )
        )
    }

有人能告诉我为什么Success()会显示这个警告吗？
