Widget Not visible - Blank space

[DOCaCola]

Current Behavior

Adding the LED widget to a page only shows a blank space. There is neither a Label or LED shown. Inspecting the element with the browser's dev tools also confirms that there is no HTML outputted to the page.
Feeding the led node some input data didn't make any difference.

I am a first time user of the LED widget, so i can't say if this is something that broke recently (or is something completely different on my end)
Using ui-led v1.1 and Dashboard 2 v1.21.0

Expected Behavior

The LED and its label should appear on the page.

Steps To Reproduce

Place a LED widget and then open the dashboard. There is only a blank space where the LED should be displayed.

Environment

• Node-RED Dashboard 2.0 version: 1.21.0
• Node-RED version: 4.0.8 (docker version)
• Node.js version: latest in official node red docker
• Platform/OS: docker
• Browser: Chrome latest

Have you provided an initial effort estimate for this issue?

I can not provide an initial effort estimate

Hi @DOCaCola - we used to have an issue whereby a restart of the Node-RED editor was required after installing the LED node, however we had resolved it.

Curious to know if a restart fixes the issue now?

I installed on nodered 4.0.3 first - after it didn't work there i went to 4.0.8 to confirm it is not an issue with the older version. Restarted the 4.0.8 nodered container several times since then as well. But no success.

This is the generated HTML of the LED node on the dashboard
<div data-v-bbe7e22d="" id="nrdb-ui-widget-57ee0d0ee97ad33e" draggable="false" class="nrdb-ui-widget nrdb-ui-led" style="display: grid; grid-template-columns: minmax(0px, 1fr); grid-template-rows: repeat(0, minmax(var(--widget-row-height), auto)); grid-column-end: span min(6, var(--layout-columns));"><!----><!----></div>
