TypeError: animationFrame is undefined Phaser 3.22

[RahulS]

So I have made a game with multiple animatons using phaser for feature phones. The game runs fine on the browser but when i build it for web application. It gives me a “TypeError: animationFrame is undefined”. When i logged anims in the console, I have all my animations and all my frames in browser mode but no frames for my animations in the built mode. Cant figure out why. Hope somebody can help me out.
