HomeBridge quits on error 'tls.convertNPNProtocols is not a function'

[ronzelver]

Since I installed the latest version (2.1.0) HomeBridge no longer starts, in the logfile I see the following statement:
TypeError: tls.convertNPNProtocols is not a function
followed by
Oct 11 20:45:34 SACLRPi3 systemd[1]: homebridge.service: Main process exited, code=exited, status=1/FAILURE Oct 11 20:45:34 SACLRPi3 systemd[1]: homebridge.service: Unit entered failed state. Oct 11 20:45:34 SACLRPi3 systemd[1]: homebridge.service: Failed with result 'exit-code'.

When I remove this plugin HomeBridge works.

Strange. Which version of Node are you using? And which other plugins?

[ronzelver]

Node version v8.9.4
Other plugins:

• homebridge-broadlink-rm v3.5.5
• homebridge-config-ui-x v3.8.11
• homebridge-daikin v0.1.4
• homebridge-foscamcamera v0.3.1
• homebridge-homewizard v0.0.59
• homebridge-lifx-lan v0.2.6
• homebridge-rpitemp v0.1.0
• homebridge-platform-ring-video-doorbell v0.12.1

[ronzelver]

I've reinstalled v2.0.0 and now it works without problems (with the above mentioned other plugins)

[robertklep]

My guess is that one of the other plugins, or one of its dependencies, might be using tls.convertNPNProtocols, which has been deprecated.

To prevent a dependency of homebridge-nefit-easy from using it, I assign null to it, but it looks like that is breaking something else. Reverting back to v2.0.0 will solve that issue, but v2.0.0 will cause other problems.

Do you have a larger stacktrace for me?

Hi Robert,

I have the same problem.

[robertklep]

@gladiatormax same questions: which Node version are you using, and which other plugins?

[gladiatormax]

I am using node version 8.12.0 with,

homebridge-zp v0.2.35
homebridge-wol v3.2.4
homebridge-samsungtv-control v1.1.1
homebridge-milight v1.1.4
homebridge-harmonyhub v0.3.0-alpha.2
homebridge-config-ui-x v3.8.11
homebridge-camera-ffmpeg v0.1.8
homebridge-broadlink-rm v3.5.5

[robertklep]

Since there's an overlap in the plugins that you both use, the problem might be caused by either homebridge-broadlink-rm or homebridge-config-ui-x.

Could you try and remove each one (separately) to see is the problem goes away?

[gladiatormax]

I reinstalled everything with nodejs version 8.12.0 because the zp pluging was asking for it and now it is working.

[robertklep]

@gladiatormax thanks for the update :) does sound like one of the other plugins needed to be updated.

@robertklep
I have somebody that has trouble with the node-red version of the nefite-easy pulign that also uses nefit-easy-core. He is using it within HomeAssistant/Hassio.
RaimondB/node-red-contrib-nefit-easy#9

Seems to be the same cause?
Do you know what plugin was the cause?

In Nefit-easy-core, there is this line
require('tls').convertNPNProtocols = null;

That is the one you are mentioning I think?

[robertklep]

@RaimondB yes, that line is likely to be causing the problem (in another Node.js module).

I have to admit that assigning that function to null is a bit of a hack, but it's required to get nefit-easy-core to work properly. However, it has always been an undocumented function to begin with, so shouldn't really have been used anyway.

I can't definitively say what's causing the error for your user, also because there are a lot of moving parts to their setup (Hassio, Node-RED, possibly other nodes that they have installed).

[ronzelver]

I solved the issue by upgrading to node version v8.16.0. Version 2.1.2 of the plugin is now running fine.
