Cannot paste into Guacamole WebGUI

[edofullin]

As title says, using image maxwaldorf/guacamole:latest paste seems to be not working. I'm not talking into RDP or SSH sessions in guacamole but into guacamole fields (including login, settings, session clipboard, etc) like in those websites where you cannot copy-paste the confirm email or password text field.

I'm using a custom guacamole.properties to enable openid and use an external postgres DBMS (the future plan is to compile a custom image without postgres, but I have this problem on both the custom image and the original)

I do not know where to look to solve this, tried with multiple browser, clearing cache and from multiple computers.

Thanks in advance!

Custom guacamole.properties:
