This error occurs in the NicheBlasta application when the official YouTube APIs are not authenticated for uploading videos.
Resolution Steps:
1. Authenticate the official YouTube APIs to ensure proper functionality.
(Tutorial to setup official API:

2. PDF: https://www.dropbox.com/s/l9cvhtrktrd8jvg/Create%20Youtube%20API%20Key.pdf?dl=0 )
2. Re-import the YouTube account into the project or create a new project and import the account after authentication.
Important Note:
If the account is associated with multiple channels, ensure that the same channel selected during authentication is used while importing. Attempting to upload videos using a different channel from the project section will result in an error.
This ensures seamless video uploads without encountering further issues.
