400 Bad Request nginx in joining a session

[cod3r0k]

When I update one of my BBB to alpha-2.3.7 , I check server with bbb-conf --secret api-mate.
After I create a session in api-mate, I try to join as a moderator or attendee. At that time I get an error as below

400 Bad Request
nginx

To Reproduce
Steps to reproduce the behavior:

1. Update to BBB 2.3.7 alpha
2. Create a session in api-mate
3. Join as moderator or attendee
4. See error

Maybe it is related my previous setting in nginx @basisbit . Isn't it? @antobinary

/var/log/nginx/error.log

2021/02/20 12:00:39 [error] 23113#23113: *340 open() "/var/www/bigbluebutton-default/client/conf/config.xml" failed (2: No such file or directory), client: x.x.x.x, server: xxxxxxxxxxxxxxxxxx, request: "GET /client/conf/config.xml HTTP/1.1", host: "xxxxxxx"

Hmm ... we're seeing the same error. Taking a closer look.

A clean install works, but the upgrade breaks. Looking closer.

I found the solution as @antobinary said at release notes.
https://github.com/bigbluebutton/bigbluebutton/releases/tag/v2.3-alpha-7

Note that we removed the recently introduced in 2.3-alpha5 instanceId from the HTML5 client's url. You may need to edit the following two lines in /usr/share/bbb-web/WEB-INF/classes/bigbluebutton.properties if you are updating an existing 2.3.x server.

- defaultHTML5ClientUrl=${bigbluebutton.web.serverURL}/html5client/%%INSTANCEID%%/join
+ defaultHTML5ClientUrl=${bigbluebutton.web.serverURL}/html5client/join
- defaultGuestWaitURL=${bigbluebutton.web.serverURL}/html5client/%%INSTANCEID%%/guestWait
+ defaultGuestWaitURL=${bigbluebutton.web.serverURL}/html5client/guestWait`

and also change all files in /etc/bigbluebutton/nginx and it works well!

@ffdixon tweaked the bbb-install script too, so this should be fine

I am encountering in my development error: ValidateAuthTokenRespMsg: Error: Match error: Expected number, got undefined

I have 2.3apha4 installed in production and 2.3aplha7 for development.

Thanks.
