Hello @hgoncalves,

thanks for opening this issue, what Vaadin Version are you using ?

The error you see is just a note, which can be ignored completely. It just tells you that the ace.js file (which is the base of this whole project) will just be deoptimised, that the size gets decresed.

Could you please show me the link you use in the browser to open the view that contains the ace editor ?

Thanks in advance,
David

Hello @F0rce we are using version: 14.6.3 of Vaadin

I unfortunately have no unprotected route that you could access to see the message.

https://our-domain/ace-builds/src-min-noconflict/theme-chrome.js
https://our-domain/ace-builds/src-min-noconflict/mode-json.js

Build for prod locally we also have the issue.

Thanks for your help,
Hugo

@hgoncalves,

no worries, I didn't mean to access your site. Could you try switching to Vaadin Version 14.6.6 with which the component has been packaged and published to the directory and are you making changes to the <AceEditor>.setBaseUrl() Method ?

I'm always here to help ;)
