TypeError: Cannot read property 'state' of null

[FezVrasta]

Describe the bug I get an error, apparently randomly, when I use the "server-state-changed" node.

31/07/2018, 20:07:50node: clean guestsroom
msg : error
"TypeError: Cannot read property 'state' of null"

If I click on the error it points to the server-state-changed node, it happens with any node of this type I have in my flows.

To Reproduce Steps to reproduce the behavior:

1. Use a server-state-changed node in any flow

Expected behavior No errors

Environment (please complete the following information):

• Node Red Version: 0.18.7
• NR Home Assistant Plugin Version: 0.3.2
• Is Node Red running in Docker: No

Other (please complete the following information):

• Have you searched previous issues for duplicates?: yes
• Did you attempt to reproduce the issue in the dev docker environment, if so what were results (See README.md): n/a

You might look at Spartan's 117 fork here, which has a fix for this:

https://github.com/Spartan-II-117/node-red-contrib-home-assistant

The original maintainer here seems to be AWOL.

Thanks for the reply! How do I install the fork? Can I find it in the Node-RED palette manager, npm or do I have to install it manually?

It's not published to NPM yet so you would need to install it manually. You can look through this thread on reddit if you get stuck:

@FezVrasta Please don't follow my old install method though, it leads to problems. You should do it this way instead: https://www.reddit.com/r/homeassistant/comments/8xyrfe/node_red_just_wanted_to_share_a_great_fork_i_found/e3y0qqu/
