Node is completely broken with OpenHab Version 3 Milestone 2

I haven't been able to track down the problem just yet but the node fails to communicate with the REST API. It appears to be an authentication problem.

Error messages include:

  • "Cannot destructure property 'state' of 'undefined' as it is undefined."
  • "Error: Request failed with status code 401"

Node was working fine with Version 2.

From what I can establish, OpenHAB Version 3 Milestone 2 does not accept anonymous REST API calls any more - not sure if this is intentional or a bug.
The credentials configuration in this node does not seem to be working. I can enter my credentials in the config node but they do not get saved and are blank when I return to the config node settings. A packet dump of the traffic between this node and OpenHAB shows that the credentials are missing from the API request header.

Thank you for your elaborate feedback, I will try to investigate this issue - if you happen to have found a working solution for this I would be happy to accept a PR.

I haven't been able to find proper documentation (yet) on the new REST API and how to properly authenticate against it. (It uses a bearer token that needs to be acquired - but I'm not sure if you can also authenticate using a regular username and password combination)

If you have more info I would be happy to look into it - I'm a bit short on time due to several other projects I'm currently working on.

@QNimbus
Milestone2 added support for basic auth, but its not working in node-red for some reason.
I also have Blue iris, and there I used token.

I've worked it this was
http://TOKEN@/items/ITEMNAME

If i'll add the token to flow.json "username":"token" I can get a list of items, but after some deployment its gone :(

I found out the following for the rest api:

subscribtion to events the smarthome has been replaced by openhab:
"/rest/events?topics=smarthome/items", {}); has to become "/rest/events?topics=openhab/items", {});

Put and post requests need the following header:
Knipsel

I tested this on the openhab2 contribution

to retrieve item states by the get method, post, or put requests to update items authentication is not need

Hope this helps
