无法通过Docs API向新的Google文档添加文本

Question

我的程序正在创建文档，每个文档都有需要输入的文本。任何尝试调用InsertTextRequest的操作都会引发错误。

List<Request> requests = new ArrayList<>();

requests.add(new Request().setInsertText(new InsertTextRequest()
                .setText("Simple test.")
                .setLocation(new Location().setIndex(0))));

BatchUpdateDocumentRequest body = new BatchUpdateDocumentRequest()
                .setRequests(requests);

BatchUpdateDocumentResponse response = docService.documents()
                .batchUpdate(file.getId(), body).execute();

Exception in thread "main" com.google.api.client.googleapis.json.GoogleJsonResponseException: 400 Bad Request
{
  "code" : 400,
  "errors" : [ {
    "domain" : "global",
    "message" : "Invalid requests[0].insertText: The insertion index must be inside the bounds of an existing paragraph. You can still create new paragraphs by inserting newlines.",
    "reason" : "badRequest"
  } ],
  "message" : "Invalid requests[0].insertText: The insertion index must be inside the bounds of an existing paragraph. You can still create new paragraphs by inserting newlines.",
  "status" : "INVALID_ARGUMENT"
}

即使尝试在添加文本之前添加换行符也不能解决此问题。

List<Request> requests = new ArrayList<>();

requests.add(new Request().setInsertText(new InsertTextRequest()
                .setText("\n")
                .setLocation(new Location().setIndex(0))));

requests.add(new Request().setInsertText(new InsertTextRequest()
                .setText("Simple test.")
                .setLocation(new Location().setIndex(0))));

BatchUpdateDocumentRequest body = new BatchUpdateDocumentRequest()
                .setRequests(requests);

BatchUpdateDocumentResponse response = docService.documents()
                .batchUpdate(file.getId(), body).execute();

这也会调用相同的错误。如何正确添加文本？​​

将Location对象的索引设置为1，因为它是1索引的。
