Cannot join a scalelite room

[rabser]

I´ve installed greenlight 3.6.1 in standalone with docker, connecting an old scalelite 1.1.8 with old BBB servers v2.3 (I can't update them by now). All things seems fine, I can create rooms and greenlight seems to work correctly. When I try to join the room, the bbb server (the real one, not scalelite) where the room it's opened (verified) I get "invalidPassword" from the BBB server and in effect in the join link I can read "password=&role=Moderator", so the password field it's empty. I would like to understand if there's anything that I can do to solve this, or I need to wait for a mandatory upgrade on scalelite/BBB.

thanks in advance for any hints.
