Nothing is sent to my dropbox from my server

Hi everyone, this is my first post here. I have been trying to install jitsi and jibri on my ubuntu 16.4 virtual server for days. After many attempts and guides, I finally managed to have jitsi working on my server, even jibri senbra working, as now the recording starts without errors.
my problem now is that after I authenticated myself on dropbox and started recording, the file is not sent to dropbox, the file is present on the server, so jibri seems to do its job correctly, but not to send to dropbox. Can you help me and tell me how to solve the problem? thanks

I solved:

apt install jitsi-upload-integrations

“finalize_recording_script_path”: “/usr/bin/” in /etc/jitsi/jibri/config.json
