Google API V3: videosInsertRequest.UploadAsync returns “Response status code does not indicate success: 400 (Bad Request)”

问题

Last Friday, execution of videosInsertRequest.UploadAsync in my EXE worked fine. Today, Monday, two exceptions are returned via the Response_Received event handler: Response status code does not indicate success: 400 (Bad Request). followed by Value cannot be null. Parameter name: baseUri.

Execution of GoogleWebAuthorizationBroker.AuthorizeAsync, ChannelsResource.ListRequest, VideoCategoriesResource.ListRequest continue to work fine.

There has been no change in the program's code over the weekend.

Any ideas?

This problem was caused by my error. I am sorry for the false alarm.

I had queued a video in my database using the Google API V2 version of my program. That version of the program stored the CategoryId in my database differently than the API V3 version.

I would like to be able to report the actual error returned (InvalidCategoryId) but have been unable to find where I can retrieve that using the .NET Client library.

From Fiddler:

{
 "error": {
  "errors": [
   {
    "domain": "youtube.video",
    "reason": "invalidCategoryId",
    "message": "Bad Request",
    "locationType": "other",
    "location": "body.snippet.categoryId"
   }
  ],
  "code": 400,
  "message": "Bad Request"
 }
}
