How to Resolve the NoLinkedYoutubeAccount Error 401 When Uploading Videos in Java

How can I fix the NoLinkedYoutubeAccount error 401 when using Java to upload videos to YouTube?

The NoLinkedYoutubeAccount error 401 typically occurs when trying to upload videos to YouTube via Java but the associated account is not properly linked to YouTube. This issue may arise due to incorrect OAuth 2.0 authorization or the Google account settings. Below are detailed steps to troubleshoot and resolve this error.

// Sample code to initialize YouTube API with OAuth 2.0
authorize.setCredentials(new GoogleCredential().setAccessToken(YOUR_ACCESS_TOKEN));
YouTube youtubeService = new YouTube.Builder(httpTransport, jsonFactory, authorize)
        .setApplicationName(APPLICATION_NAME)
        .build();

// Upload video method
def uploadVideo(File videoFile) {
    YouTube.Videos.Insert request = youtubeService.videos().insert(
        "snippet,status",
        videoObject,
        mediaUpload);
    request.execute();
}

Causes

• The Google account is not linked to a YouTube channel.
• The OAuth 2.0 credentials are incorrectly set up or expired.
• The user does not have permission to upload videos.

Solutions

• Ensure that your Google account is properly linked to a YouTube channel by visiting YouTube settings.
• Double-check your OAuth 2.0 setup in the Google Developer Console and ensure that your application has permission to access YouTube Data API v3.
• Make sure that the user account you are using has the necessary permissions to upload videos.

Mistake: Using an outdated access token.

Solution: Generate a new access token with the required scopes and try again.

Mistake: Not linking the Google account to a YouTube channel.

Solution: Ensure your Google account is linked to a YouTube channel through the YouTube settings.

Mistake: Incorrect API scopes in the OAuth configuration.

Solution: Verify that you are using the correct API scopes for video uploads.
