Bulletproof yellow diamond

Hi, I have configured the plugin correctly but whenever I launch the action a yellow diamond appears. I don't know what else I can do. I have enabled <label for="files.content.write">files.content.write and </label><label for="files.content.read">files.content.read on dropbox app,as the logging told me, but now I'm stucked with this message.</label> <label for="files.content.read"> [21-Oct-2022 10:53:18 UTC] Chunked upload exception (Dropbox_BadRequestException): Error in call to API function "files/upload_session/append:2": HTTP header "Dropbox-API-Arg": cursor.session_id: 'None' expected to be a string, got null (line: 209, file: /home/fisio/web/fisioterapiatualcance.com/public_html/wp-content/plugins/bulletproof-videos-youtube-channel-backup/res/Dropbox2/OAuth/Consumer/Curl.php) [21-Oct-2022 10:53:18 UTC] Failed to upload file to /Bulletproof YT/3 tracciones para descomprimir tu espalda en menos de 1 minuto.mp4 (see log file for more) </label> Could you give me a hand? Thanks.
