当我尝试以PDF/Excel/Word或打印报告导出报告时,出现错误.错误说明:

我必须在一个multiline字符串中传递一个字符串(逐字)mutation.我必须在单独的应用程序中回读文本并将其另存为文本文件.
这是我想要做的.我正在尝试使用GraphiQL客户端与测试服务器通信GraphCool.
mutation {
createMessage(fullName: "John K",
message: "some very long text
message that appears on multiple lines
with line breaks."
}
我得到了这个错误
{
"error": "Syntax error while parsing GraphQL query. Invalid input \"\"some very long text\\n\", expected StringValue, BooleanValue, NullValue, Variable, Comments, ObjectValue, EnumValue, NumberValue or ListValue (line 6, column 13):\n message: \"some very long text\n ^"
}
我可以用\n替换所有换行符来解决问题.
mutation {

目前的屏幕捕获代码是：
private void CaptureMyScreen()
{
try
{
//Creating a new Bitmap object
Bitmap captureBitmap = new Bitmap(1024, 768, PixelFormat.Format32bppArgb);
//Creating a Rectangle object which will capture our Current Screen
Rectangle captureRectangle = Screen.AllScreens[0].Bounds;
//Creating a New Graphics Object
Graphics captureGraphics = Graphics.FromImage(captureBitmap);
//Copying Image from The Screen
captureGraphics.CopyFromScreen(captureRectangle.Left, captureRectangle.Top, 0, 0, captureRectangle.Size);
//Saving the Image File (I am here Saving it in My D drive).
captureBitmap.Save(@"D:\Capture.jpg", ImageFormat.Jpeg);
//Displaying the Successfull Result
MessageBox.Show("Screen Captured");
}
catch (Exception ex)

但是一旦我为datastore模拟器设置环境变量,并重新启动本地App Engine,它就会因错误而崩溃,
Caused by: java.lang.IllegalStateException: Must use project ID as app ID if project ID is provided.
我在下面附上了一个更完整的堆栈跟踪
从错误消息中,我怀疑我需要将项目ID更改为项目名称.所以我尝试用我可能的项目名称替换项目id的各种实例,不幸的是,这也没有用.
我正在运行的命令:
1. gcloud config set project PROJECT-ID
2. export ENDPOINTS_SERVICE_NAME=name.endpoints.PROJECT-ID.cloud.goog
3. gcloud beta emulators datastore start
4. $(gcloud beta emulators datastore env-init)
5. mvn appengine:run
我把堆栈跟踪放在pastebin https://pastebin.com/atcnYwrq上
