"Failed to execute 'animate' ... no function was found that matched" after 2.2.0

I'm testing this on a fairly new Android 5.1.1 browser with a WebView of 44.0.2403.133 and using this code:

this.element.animate({
  opacity: [0, 1]
}, {
  duration: 300,
  fill: 'forwards'
});

That code fails on that environment with Uncaught TypeError: Failed to execute 'animate' on 'Element': The provided value is not of type '(EffectModel or sequence<Dictionary>)'.

I did test this code on IE11, Chrome, Firefox and Safari (all latest versions) though and it seems to work fine.

Actually scratch that, the polyfill throws a TypeError for it. It is in the docs about the API though.

Which version of the polyfill are you using? This new syntax is only present in v2.2.0.

Ah right. I did downgrade to 2.1.5 after looking at the issues lately since I thought this is connected to 2.2.0 having a regression bug.

Will test again when I have time. I'll close this for now. Thanks for the help.

Opening this again. v2.2.0 doesn't seem to work on this specific Android browser.

I also get a similar error on Android 5.0.

After just importing web-animations-next-lite.min.js from v2.2.0, there’s this error line in the console:

Uncaught TypeError: Failed to execute 'animate' on 'Element': No function was found that matched the signature provided..

Another phone with Android 6.0.1 gives this error, exactly similar to one in the first comment:

Uncaught TypeError: Failed to execute 'animate' on 'Element': The provided value is not of type '(EffectModel or sequence<Dictionary>)'

This is apparently affecting the latest release of Samsung Internet: https://play.google.com/store/apps/details?id=com.sec.android.app.sbrowser&hl=en
