Error while importing a Flow

General

So I wanted to look at the Flow from this guide.

And tried to import this flow(directly copied from the site)

But as I click on import copy this error occurs:
image
Anyone knows what to do. Because I really need to look at the Flow to embed a grafana chart into node-red-dashboard.

It works OK for me - how are you importing it ?

3

I just select import in the menu, paste the code from my clipboard. Click on Import.
Then Node-Red tells me some of the nodes already exist, thats where I click on import copys and bam! the error is appearing. It is also not my first node I am importing I never before encountered such a problem while importing nodes.

4

Okay so I did try to import this many times. always with the error. Than I saw the nodes where in my flows but I had 5 on top of on another (I did not realise it at first and hitted deploy, I got a warning->see below) so I deleted all of them. And still I got a warning, my flows stoppped. I restarted node-red. And this is what I see:
image
So I see the same error as before and something about a missing node type.
And I just dont know what to do, I deleted the flows completely, the error stays. I dont anywhere in my node-red have a graph node, and the error from adding flows just stays there altough I restarted node-red.
It just feels like I destroyed ma nodered completely

5

I have node red running in a console it displays:
image
Anybody knows what to do?

6

It is probably a configuration node. Select Configuration Nodes in the menu, click Unused and select and delete anything there.

I deleted the configuration node, but the error still is here.
This is what I can read in my console:

I searched my flows, nowhere is a graph node. And the Error adding flows is still there altough I did not try to import something today, it seems like it is stuck but i dont know what i should do to fix this.

It says something with using the CLI flag --unhandled-rejections=strict But I dont know where I can use that.

8

I tried something in the command line using node. But using --unhandled-rejections=strict did nothing, and i cant seem to read useful information from the website that was recommended.(is written behind the --unhandled-rejections=strict)

9

Okay I tried some things in the cmd line, I would get a error everytime i write something because I just dont know how to work with this. But then once it just did not give me an error I thought it just did nothing and carried on. Then I gave up closed node-red and decided to start it one more tima. And It seems as its working again.

I really dont know what happened. But I am glad it works again. And I am now scared to try to import the flow again, I think i just let it be

10

That will have been nothing to do with it.
