I see that guacamole-client uses ‘ManagedClient.sendArguments’ but sendArguments’ needs to receive ManagedClient so I’m not sure how to use it in my code.

I’m trying to add support to the “required” request for parameter prompting, I added this code to my client: let client = new Guacamole.Client(tunnel) client.onrequired = function(params) { … client.send(credentials); } For some reason, no matter what I send through the credentials, guacd don’t seem to accept them. Do I need to disconnect from the client and then connect again with the credentials? Can someone please help me and maybe provide an example for and .onrequired? The official Guacamole Client code uses this: https://github.com/apache/guacamole-client/blob/78e0436dc202673686dc8a7741eca6cb21513d77/guacamole/src/main/frontend/src/app/client/types/ManagedClient.js#L720-L728<https://protect.checkpoint.com/v2/r02/___https:/github.com/apache/guacamole-client/blob/78e0436dc202673686dc8a7741eca6cb21513d77/guacamole/src/main/frontend/src/app/client/types/ManagedClient.js%23L720-L728___.YzJlOmNwYWxsOmM6bzo1M2RhZWQyNTY1NWNiZDZkMzc3ZjBjNjc4Y2M1MjkxYzo3OmIzMzI6MzA2YTM4YjUxNjhhNDhlNjU5MTc4MWQ4YTlhYWM3OTY4ZjVjZjZmNTVhNzI0NjcxYThjNTU2YjRmNTQ2MDUyNjpoOlQ6Tg> I'd highly suggest going through the Guacamole Client code, particularly for the AngularJS front-end, to see how it is handled in there - this block only takes care of letting the client know that a required instruction has been sent and prompting the user - you have to go to a couple of other places to see where the user is actually prompted and where those responses are actually sent back to guacd. And to answer your question, no, there is no need to disconnect and reconnect - in the cases where guacd sends the "required" instruction, it is usually because there is a call-back function from one of the supported protocols being invoked that needs more information and is now waiting on that information to be provided. I know that's a very high-level answer - feel free to post back with more specific/detailed questions. -Nick
