I suddenly started receiving a warning every time I Deploy saying,
_“The workspace contains some nodes that are not properly configured:” and referring to a Dashboard stylesheet (ui\_template) which has the little red pyramid warning._
I have made no change to this node – it is just a CSS collection to generate rounded corners on Dashboard.
I decided to check for upgrades and now have v1.3.5 but no change.
At the command prompt I get 2 x DeprecationWarnings but I have absolutely no idea of what to fix and how, etc.
The Command window listed below gives the following output:
_C:\WINDOWS\system32\>node-red [Command prompt]_
_(node:2220) [DEP0128] DeprecationWarning: Invalid 'main' field in 'C:\Users{username}\AppData\Roaming\npm\node\_modules\node-red\node\_modules@node-red\editor-client\package.json' of './lib/index.js'. Please either fix that or report it to the module author_
_(Use `node --trace-deprecation ...` to show where the warning was created)_

I must say that everything appears to be working on the Dashboard.
Any guidance will be greatly welcome!

Have you assigned the ui-control to a valid group and tab and redeployed?

Many thanks for your kind assistance.
Template Properties originally said;
Template Type : _Added to site section_
Name : _Dashboard stylesheet_
I then changed it to "Widget in group" and selected an operational group and deployed.
Brilliant! Both the red icon and the error warning disappeared upon deployment!
Checking the selected group, the CSS has an effect but not globally. I reverted to the original settings and all still seems to be fine with the CSS applied globally. I'm not sure this is good practice. Perhaps I should set a template for each Group?
I am still getting the start-up deprecation warnings x 2 and really don't know if they are serious or can be disregarded?

You can ignore that one, that is because you are using nodejs 16, which causes this warning.

Apologies to anyone who stumbles across this - I made the error of asking 2 different questions within a single posting without realising they were unrelated. Very fortunately both were kindly answered.

At the time you had no way of knowing they were unrelated.
