BigBlueButton integration not working

Description:

The BigBlueButton integration in RC is not working. Users are authenticated on RC aswell as on bbb using openLDAP (the LDAP for the both of them)

Steps to reproduce:

Installed my own bbb server, everything is working fine on the instance, but when I activate the bbb integration in rocketchat and try to start a video call from a channel, the sidebar pops up with the "Start Meeting" button" but when you click on it, nothing happens

Expected behavior:

A bbb video call window should popup and start a video conference

Actual behavior:

nothing except an error in the devtools

Server Setup Information:

• Version of Rocket.Chat Server: 1.0.3
• Operating System: Ubuntu 18.04
• Deployment Method: snap
• Number of Running Instances: 1
• NodeJS Version: NA
• MongoDB Version: NA

Additional context

All instances are in the AWS env, the LDAP, the RC and the bbb
the bbb insstance and the RC instance authenticate users from the same LDAP

The default domain is set in the LDAP settings, I don't understand why this warning is in the logs

Start by reproducing the BigBlueButton meeting failure and reviewing the LDAP error reported at app/ldap/server/sync.js:290, along with the client 500 response. Trace how the LDAP account is created when the BBB integration starts. Done means the cause is identified and a verified configuration or code fix allows the meeting window to start successfully.
