Error when using lottie

Hello!

The Lotie files used by Webflow have completely disappeared from designer mode

As soon as you press the rotifile setting on Navigator, a webflow error occurs and is refreshed with the log transfer button.

As soon as you upload Asset again and add it to the page, a webflow error occurs again, and you cannot touch the lotie file itself.

However, when I publish it, it shows normal operation (but I can’t upload or modify the lotie file)… )

Does anyone have the same problem as me?

I got the free lotie file from lottiefiles.com and used it in json format.
