cssRules exception error in Mashup - TWX 9.3.4

[pshashipreetham]

In previous versions of TWX, the mashup was working fine. But when I was trying to load the Mashup in the Thingworx 9.3.4 version, the mashup doesn't show any widgets, only empty Screen can be seen!

In Console, I saw following error:

Note: Mashup contains Custom widgets.

Thanks,

Hello @pshashipreetham ,

Even if CSS is added to a specific mashup, the CSS rules could impact other elements in the page outside the mashups content. Pls refer the link for your reference:

Hey,

The Custom widgets use JS, an older version than the JS Used in the Latest Thingworx Version. Therefore, many CSS Snippets are used in the Custom Widgets that are not supported and act weirdly.

We have updated it, and that fixed the issue.

Thanks,
