为什么在Google Colaboratory中使用Python3.6在google drive.files.update中出现“错误请求”？

Question

I use Google Drive API v3 and Python3.6 in Google Colaboratory. My guess, it is an error in update_metadata, but I can't find it. https://developers.google.com/drive/api/v3/reference/files/update says these properties are writable. I'm stucked, and I need help, thanks.

def NEWshare(selected_id, email, permissions_metadata, emailmsg, send=True):                   
    drive_service.permissions().create(body=permissions_metadata,                                            
    emailMessage = emailmsg,
    sendNotificationEmail = send,
    fileId=selected_id).execute()

def NEWupdate(selected_id, update_metadata):
    drive_service.files().update(body=update_metadata, 
    fileId=selected_id).execute()

permissions_metadata = {
                        "deleted": True,
                        "emailAddress": email,
                        "kind": "drive#permission",
                        "role": "reader",
                        "type": "user"
                       }

update_metadata = {
                   "copyRequiresWriterPermission": True,
                   "writersCanShare": False
                  }

The NEWshare(selected_id, email, permissions_metadata, emailmsg, send=True) works well. Now I want to update with NEWupdate(selected_id, update_metadata), but I obtain the error message

For this error " HttpError: <HttpError 400 when requesting https://www.googleapis.com/drive/v3/files/1n8k_4fY4KMM9gnqD2MPvvV8cRgY0yCRd?alt=json returned "Bad Request"> ", a refresh request needs refresh_token , client_id , client_secret , and grant_type . Here is the documentation on refreshing an access token . See this github post .
