FreePBX 16 - UCP Node not runnung

[sharbich]

Hello, my dears,
I installed FreePBX 16 with Asterisk 16 on Debian 11. I can successfully access my FreePBX Admin Dashboard.

However, I get a critical error. This reads as follows in the dashboard: “UCP Node is not running”. In the “ucp_error.log” I see the following error messages:

Can you help me? What can I do?

UCP’s node service has older dependencies so you will have to downgrade node if you want to use it. FreePBX distro has node v8.16.0. Alternatively, you can use UCP without the node service.

Hello, how can I use UCP without node service?

[domosute]

Yeah… very similar message I encountered a couple of weeks ago…
I guess you need to downgrade the NodeJS version.
Hopefully below helps.

New FreePBX install setup on Rocky Linux 9.1

Ah, I finally figured out the UCP Daemon error. I was seeing error when I perform fwconsole ma downloadinstall ucp, the script stopped with compilation error and it was due to the dependency module, mariasql. As in the below link, the build failed if nodejs version is 12 or greater. https://ci.appveyor.com/project/mscdex/node-mariasql Apparently, this module is failing the build with newer nodejs version, and Rocky Linux 9 comes with version 18 as default, (as of 4/27/2023) and I could not ins…

Hello, I’ve read that the Nodej version can be stepped down with the command “nvm install version number”. Did someone try it out?

[domosute]

I tried nvm, but it wasn’t working well on Rocky Linux 9 platform, so I am using n version manager instead.

[sharbich]

How would the version manager be the complete command to downgrade?

Hello, I downgraded to nodejs version 8.16.0 with the command “n 8.16.0”. Unfortunately the error still exists. In the logging I see a different message now:

Do you have another tip for me?

[domosute]

Version 8 didn’t work for me as well, as I mentioned, 10.24.1 worked for me, but it could be different scenario for you. have you done fwconsole ma downloadinstall ucp to force reinstall the module?

[sharbich]

Hello, I was able to solve the problem with the following commands:

apt remove nodejs
apt install nodejs
fwconsole ma download ucp
fwconsole ma install ucp
fwconsole reload
systemctl restart freepbx.service

Congrats! For my case, RL9 came with version 18 of NodeJS, I needed to downgrade for ucp to work, but if you can stick to the host server’s package manager, that’s the best!
