Uncaught TypeError: Illegal constructor Error

See original GitHub issue

Hi,

I am getting this error:

Uncaught TypeError: Illegal constructor
    at n (prism.js:1)
    at prism.js:1
    at prism.js:1
    at Array.forEach (<anonymous>)
    at Prism.plugins.toolbar.hook (prism.js:1)
    at Object.run (prism.js:1)
    at Object.highlightElement (prism.js:1)
    at HTMLDocument.highlightAll (prism.js:1)

It seems to be showing when I add the “Copy to Clipboard Button” package.

My browser I am getting the error is Google Chrome Version 62.0.3200.0 (Official Build)

Here is a screenshot of the error in dev tools:

For now I am just going to live with out adding this plugin. I thought I’d let you know anyway.

p.s. Normal setup works fine no problem. It only appears with this plugin addon.

@caraya Thanks, that might be it, but Chrome 61 (or 63) doesn’t have a navigator.clipboard property. I’m still not sure the cause.

Update: Yes, the window.Clipboard prototype matches the Clipboard inteface in the spec, so this must be an early introduction as they build out the infra for this Clipboard api.

Just so everyone knows, this can be resolved by including Clipboard.js yourself, either in a script tag or bundled into your JS. It’s specifically the plugin’s behavior to fallback to a CDN version if it doesn’t find Clipboard.js that is failing.
