Re: Error 404 with Guacamole 1.5.2

[Xuo]

Hi,


Now, I've got another one.

journalctl --since 09:17

ERROR o.a.g.rest.RESTExceptionMapper - Unexpected internal error:


And some more lines.
I've search during the whole week-end without success.
If you have any idea, I'll be glad to test it.

directory /etc/guacamole/extensions :


directory /etc/guacamole/lib :

-rw-r--r-- 1 guacuser guacuser 2493165 juil. 15 09:37 mysql-connector-j.jar

mysql-connector-j.jar corresponds to the version of MariaDB connector/J3.1.4

When working with guacamole 1.4 :

directory /etc/guacamole/extensions :


directory /etc/guacamole/lib :






*
Even though in my guacamole.properties, there is :
mysql-driver: mariadb
mysql-hostname: localhost
...

Regards.

Xuo.

After more than 3 weeks without any internet connection (except through my phone), I can now try to debug again my issue. To summarize, you were right. If I keep only one single extension, the error disappears. juil. 15 09:17:47 ordi4 server[1272619]: 09:17:47.453 [http-nio-8080-exec-4] WARN  o.a.g.e.AuthenticationProviderFacade - The "mysql" authentication provider has encountered an internal error which will halt the authentication process.

Stupid guess, but can you also check the content of your guacamole/extensions directory?

Some extensions (looking at you, TOTP) will make Tomcat crash with this exact error if multiple versions are loaded.

We should add an additional sanity check to warn if this condition is detected, but FYI: The reason multiple copies of the same extension cannot be loaded at the same time is their namespaces will collide. Every extension defines a unique namespace to isolate itself from others. If that namespace isn't actually unique, then resources/endpoints declared by those extensions will have conflicting paths, causing webapp startup to fail.
