First, you should know how to ask a question. And that is not like you did it.
Second, you don’t tell anything just post a few blocks. Even now you don’t tell anything except that some lottie file is not working.
How do you expect us to help you? We are no wizards or mind readers. We have told many users that many times before.
Show the lottie file. Post for instance an aia with the lottie file inside for others to test. Show error messages.
So if you want help you have to work for it.
