browser console error:Uncaught (in promise) ReferenceError: unsafeCSS is not defined

but if i remove tooltip lib ,not error!

When I use vaadin 23,it’s error ,

note:target ->generated-flow-imports.js

export const addCssBlock = function(block, before = false) {
const tpl = document.createElement(‘template’);
tpl.innerHTML = block;
document.head[before ? ‘insertBefore’ : ‘appendChild’]
(tpl.content, document.head.firstChild);
};

import $cssFromFile_0 from ‘tippy.js/dist/tippy.css’;
const $css_0 = typeof $cssFromFile_0 === ‘string’ ? unsafeCSS($cssFromFile_0) : $cssFromFile_0;
addCssBlock(<style>${$css_0}</style>);

Hi

I tried reproducing the issue using this [demo]
(https://gitlab.com/gsedlacz/tooltips4vaadin/-/tree/master/demo) but no error shows up.

What else needs to be done to provoke the message?

Kind Regards

Gerrit Sedlaczek,thanks for your reply,
I rebuild the project ,now the error is not throw.
But i don’t know the reasons.

After I add de.f0rce.ace to vaadin.whitelisted-packages ,This error does not occur。
