That is odd indeed.
Can you export that flow for others to test please?

What version of nodejs are you using? Use node -v to find out. If it is 14.x then it may be another instance of this issue. ["TypeError: Object.hasOwn is not a function" Error · Issue #316 · FlowFuse/node-red-dashboard · GitHub](https://github.com/FlowFuse/node-red-dashboard/issues/316)
If so then possibly the change there needs to be made in the gauge node too.

Ah, that's your problem. [Object.hasOwn](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/hasOwn) requires node v16+
Ps, node v14 is out of support as is v16. You should aim for v18lts or v20 lts

Okay, then i need to update. Is there a wiki for an easy update?

There are too many variables (like what OS, what hardware etc). Tell us what you have first.

I believe it should be fixed in the gauge node as dashboard 2 is supposed to work with v14.

I don't remember reading that.
Either way, upgrading node would fix this for the Op and it is definitely recommended as v14 is EOL 🤷♂️

Then your upgrade is simple, from the [docs](https://nodered.org/docs/getting-started/raspberrypi)
```auto
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered) --node18

Does that mean that D2 requires Node.js \>14 which is still Node-RED's baseline?

Not for long 😉
In seriousness tho, I playing in the dashboard source & spotted `Object.hasOwn` is used in the dashboard frontend vue files but they get converted to ES5 through compilation (vite config), the nodes are not & have therefore slipped through the net.
If an issue is raised on dashboard, they will get mopped up. For quick reference, `Object.hasOwn` appears twice in `ui_base.js`

Not wanting to push - but any idea of timescales for v4? I've a bunch of outstanding changes for UIBIULDER that I class as potentially breaking but I don't want to add them until the node.js baseline version also changes.

Nick was out last week but AFAIK it pretty much next on the TODO list. (Nick, jump in correct me if I am speaking out of turn)
If I were a betting man, I'd put money on \< 1 month for a v4 beta.
