PG3 ELK node server 3.5.5 fails with error: cannot import name 'FunctionKeys'

[rwsani99]

I have been using PG3 ELK node server successfully for about 6 months.  Today I noticed my Polisy v.5.4.4 was not detecting correct ELK status.  When I checked the node server it's status is 'Disconnected'.  Tried stop/start of node server, and finally reboot of Polisy, but always the same results.  I'm running PG3 version 3.0.62.  The node server attempts startup, but fails immediately with the follow error:

Any ideas?

That's odd, something must not have installed correctly, can you log into your polisy and run this?  Replace the _4 with the slot number of the ELK node server:

cd /var/polyglot/pg3/ns/*_4
sudo -u polyglot ./install.sh

 

[rwsani99]

Gave that a shot and got an error. I verified I'm in the correct slot/directory by viewing the README.md file. And I verified that install.sh exists in this directory, (ls -l).  And the contents of ./install.sh is

[admin@polisy /var/polyglot/pg3/ns/00:0d:b9:5e:e2:8c_2]$ cat ./install.sh
#!/usr/bin/env bash
pip3 install -r requirements.txt --user
 

 

 Not sure if this error is saying the install.sh is not found?  Or a line within the shell script?  And I'm assuming the 'Password:' it is asking for is the password for admin@ polisy. Again, I appreciate your help. Here's the error:

[admin@polisy /var/polyglot/pg3/ns/00:0d:b9:5e:e2:8c_2]$ sudo -u polyglot ./install.sh
Password:
sudo: ./install.sh: command not found
[admin@polisy /var/polyglot/pg3/ns/00:0d:b9:5e:e2:8c_2]$

[Jimbo.Automates]

Try this: 

sudo -u polyglot bash ./install.sh

[rwsani99]

So now I get:

[admin@polisy /var/polyglot/pg3/ns/00:0d:b9:5e:e2:8c_2]$ sudo -u polyglot bash .                                 /install.sh

Oh, that explains it.  You need to do an "Upgrade Modules" to get the latest python:

[admin@polisy-dev ~]$ python3 -V
Python 3.9.14

 

[rwsani99]

Thanks!!  That did the trick.  I did an "Upgrade Packages" from the admin console yesterday, and restarted PG3 afterwards, or so I thought.  But issuing another "Upgrade Packages" just now, followed by a Polyglot restart seems to have fixed my problems.  Really appreciate you help, and the ELK nose server!

[Jimbo.Automates]

Awesome, glad that fixed it, and you are welcome.
