Missing web-animations-next-lite.min.js

[SergRZ]

I am not able to use links in properties window when running polymer designer (https://www.polymer-project.org/tools/designer/). Looking at Chrome console output I found that possible reason for that is missing "web-animations-next-lite.min.js" followed by multiple "Animation is not defined" errors.

Is there any way to overcome this problem?

Hello,

the missing "web-animations-next-lite.min.js" error has gone and links in properties window are working now. Was it some correction from developers?
Chrome console shows new error "base64.js" is not found but nothing is affected by this error as it seems for the time being.

Yes, the name of the web animations polyfill we were depending on changed. I think the code is corrected in 0.5.2, which is now on the website.

As for the new report, it looks like the github library that designer uses removed a file, but something's still referring to it.

I filed a bug for this over here: googlearchive/github-elements#2

I'm going to close this issue since the original problem is resolved.

Thanks for the report!
