Could not retrieve YouTube upload token: 400: Upload token returned from YouTube API is null. about youtube-direct HOT 5 CLOSED

Solved. Form requires inputs to be at least 2 characters long.

Better client-side validation is needed.

I am having the same problem, getting the same "could not retrieve YouTube 
upload token: 400: Upload token returned from YouTube API is null. Please make 
sure that all request parameters are valid."

All required parameters have 2+ characters.

Problem occurred on the second and third assignments made on the same YTD 
application. I did go in and change the embed code to the proper assignment id 
as it was still the same as the first assignment. No change in the "upload 
token" error message.

Any help would be most appreciated.

Better client-side validation is now in place. If this is still an issue for 
anyone, please provide an example URL for a page containing the YTD embed where 
this can be reproduced.
