Error while connecting to openHAB REST API #57

paulianttila · 2017-11-18T10:03:20Z

VS code extension given an error "Error while connecting to openHAB REST API". File editing works fine (via samba share).

Versions:

Visual Studio code: 1.18.1
openHAB VS Code Extension: 0.3.0
OS: macOS 10.13 High Sierra

openHAB: 2.2.0~20171018133740-1

paulianttila · 2017-11-18T17:06:42Z

Items fetch seems to work at least partly. When I press refresh button from VS, item states are refreshed (not sure if all) but with same error.

Things panel doesn't show anything.

kubawolanin · 2017-11-18T18:56:39Z

Hey @paulianttila thanks for reporting!
Could you open http://192.168.10.7:8080/rest/things and see if it returns anything?
I'm relying on the REST API all the way, so if it's a problem on the distro, there's likely some log in your openhab.log file telling you what's up :-)

Try restarting your openhab instance and see if http://192.168.10.7:8080/rest/things loads in your browser. Maybe it's some issue in your *.things files?

Anyways, I'm keeping this issue open. I'll think of better error handling in that scenario.

Cheers

fseffert · 2017-11-18T21:30:21Z

Hey... same problem for me! I noticed that in my settings.json the openhab.host setting gets always overwritten with "localhost".
I can access the rest api with my browser without problems!

paulianttila · 2017-11-19T08:53:40Z

@kubawolanin, both items and things files can be fetched fine via browser and JSON is valid (tested with another tool). Also Paper UI works fine.

OpenHAB log doesn't show anything suspicious.

kubawolanin · 2017-11-19T15:04:05Z

@paulianttila @fseffert could you be so kind and test if problem still occurs on your machines with the attached extension?

openhab-0.3.0.vsix.zip
Just unzip it and install manually.

Follow this post to see how to install the extension manually from VSIX.

Cheers!

paulianttila · 2017-11-19T15:43:54Z

@kubawolanin, just tested new version. Unfortunately, with the same result. Does extension do any kind of logging?

If I press "OPENHAB ITEMS" or "OPENHAB THINGS" panels refresh icon, it downloads both items and things files nicely (seen from wireshark) but it gives the same error message. Items panel is refreshed and things panel stays empty.

kubawolanin · 2017-11-19T16:46:07Z

Hmm so the error message comes from this file which is a part of vscode's framework for tree views.

@fseffert can you share more info on your environment? Is it a Mac as well?

I've encountered some issues with the latest SNAPSHOT build so the problem could be partially related with it too. After downgrading my openHAB to distro # 1082 everything went back to normal (no weird log messages, problems with REST API endpoints loading etc).

I will, however, work on the solution on my side and hopefully we'll find what's the real issue.

In the meantime, here's the package with some more fixes on my side:
openhab-0.3.0.zip

dartrax · 2017-11-20T10:23:49Z

Hello,
I'm having the same issue. I freshly set up openHABian last weekend and Visual Studio Code with this extension. I get the same two errors in VS developer tools that @paulianttila already posted.
http://rapb-pi-IP:8080/rest/things seems to be working.
I did not test with the new vsix.

Visual Studio code: 1.18.1 x64
openHAB VS Code Extension: 0.3.0
OS: Win 10 Version 1703

kubawolanin · 2017-11-20T17:44:21Z

@dartrax what version of openHAB are you running? Is it by any chance build # 1084 or 1083? See this post for details. The build has some runtime bugs.

Please test the extension from my previous post. I will merge it and publish it as soon as I'm sure the error doesn't occur anymore.

dartrax · 2017-11-20T18:47:50Z

Hi, I have

openHAB Distribution Version Information
----------------------------------------
build-no        : - release build -
online-repo     : https://dl.bintray.com/openhab/mvn/online-repo/2.1

Repository        Version
----------------------------------------
openhab-distro  : 2.1.0
smarthome       : 0.9.0.b5
openhab-core    : 2.1.0
openhab1-addons : 1.10.0
openhab2-addons : 2.1.0
karaf           : 4.0.8

and I don't know which build number that represents.
I also tried the extension from your post. I uninstalled the old one, restart, installed it from vsix, restart, checked the settings, but still the same.

{
    "openhab.host": "192.168.178.41",
    "openhab.port": 8080,
    "openhab.useRestApi": true
    /*"openhab.username": "openhabian",
    "openhab.password": "openhabian"*/
}

kubawolanin · 2017-11-20T18:57:06Z

@dartrax looks like you're using the release build (2.1) and not the SNAPSHOT.
If the following command on your openHABian doesn't return a number, it confirms it:

sed -n 's/build-no\s*: //p' /var/lib/openhab2/etc/version.properties | cut -d '#' -f 2

If that's the case, please try to add the following line to your settings:

"openhab.lspEnabled": false

Also, there might be a need to reload VSCode window each time you change your settings.
Simply hit Ctrl + Shift + P and type "Reload window"

Cheers

dartrax · 2017-11-20T19:26:06Z

Yes, I'm using the release build (2.1)
I added that line to my settings and "reload window", but it still does not work.
One thing I noticed: Even with the setting
"openhab.useRestApi": false
I'm still getting the "Error while connecting to openHAB REST API"-Message.

paulianttila · 2017-11-20T19:31:41Z

@kubawolanin, I forgotten to inform you yesterday that I tested your latest extension without success.

kubawolanin · 2017-11-20T20:21:26Z

@paulianttila @fseffert @dartrax here's the updated extension, available also in #58.
openhab-0.3.0.zip

dartrax · 2017-11-21T09:13:27Z

I tried the updated extension. No Error message anymore, but Sitemap preview, Things and Items Panel stay empty.
Developer tools still say:

paulianttila · 2017-11-21T14:46:41Z

Updated the latest extension and behaviour is exactly same as @dartrax have.

sjsf · 2017-11-24T16:30:14Z

while trying to fix eclipse-archived/smarthome#4601 I just ran into the same issue after a couple of restarts. Maybe something got updated silently under the hood? In any case, all the openHAB windows are empty and it also doesn't even try to connect to the LSP backend anymore.

Let me know if (and how) I can help with the analysis.

kubawolanin · 2017-11-24T17:24:25Z

This bugs me because I couldn't reproduce this bug even once.
I'm running Windows 10, VSCode 1.18.1 and openHAB distro 1094.

I've pushed some changes to #58 - I would really appreciate if you could test the extension again:
openhab-0.3.0.zip

Exact steps to reproduce would be also really helpful.

jewesta · 2017-11-24T19:17:05Z

For what it's worth: I'm running a similar environment as @paulianttila except for I'm on a Raspberry and distro #1094. I have not seen this error.

I tried 0.3.0 #58 just out of curiosity. It does not change anything on my side. So I'm still getting those path / code checking / hover problems (NPEs in the logs etc.) but it does not make anything worse either.

paulianttila · 2017-11-24T19:25:17Z

@kubawolanin, just tried the latest version (also reinstalled VSCode). Items works fine, but things panel stays empty.

@paulianttila thank you!
Could you visit http://192.168.10.7:8080/paperui/index.html#/configuration/things and tell me if all your Things have labels?

kubawolanin · 2017-11-24T21:21:38Z

Ah, turns out that the Things comparator was taking only label into consideration! :-)
It's resolved now! :)

paulianttila · 2017-11-25T08:46:50Z

@kubawolanin, that's great. Do you have new version available?

kubawolanin · 2017-11-25T08:49:24Z

Sure thing! I'll prepare a new release in the next few days. In the meantime, here's the packaged VSIX:
openhab-0.3.0.zip

Thanks for your help!

paulianttila · 2017-11-25T08:53:22Z

I can also verify that thing problem is now fixed. Thank you @kubawolanin.

dartrax · 2017-11-25T12:56:49Z

LiPoPower · 2017-12-30T09:48:33Z

Hello,
same problem here
Installed openhab 2.2.0 running in a docker container under Linux , VS openhab-Extension 0.35.
The restapi seems functional, "http://raspi3:8080/rest/things" returns things.
Like to give you more info, but i'm totally new to VS Code.
Maybe you can guide me to necessary additonal info?

kubawolanin · 2017-12-30T09:57:07Z

@LiPoPower take a look at #67 - it might be related.

LiPoPower · 2017-12-30T10:17:47Z

Ups, sorry for that: did the customizations in vs user preferences. #Moved it to workspace preferences now it works like charm...

dannycohn · 2018-02-23T13:37:28Z

This problem just crept up for me. I am running 0.3.5 of the plugin. It was working fine until some time recently. I'm not sure what thing/item I might have added that caused the problem. Is there an easy way to debug to help get to the bottom of it?

mloetscher · 2018-03-23T08:27:57Z

I have exactly the same issue (openHAB 2.2, plugin 0.3.5, rest api works fine) - doesn't work with user and/or workspace preferences... Any update on this?

mloetscher · 2018-03-23T08:35:04Z

I just erased my .items file (which was only copied from the example, no correct values in it) and restarted openhab - now it works... Looks like the plugin has some issues with error handling...
