Do you have a staging link for your animation that you can share with us?
Is there any specific reason why the content header is configured as type x-js instead of js. I see the delay in loading the content with type x-js(txt_edge.js). I am not sure If this is the reason, but may be you can just try changing that to js from x-js, which was supposed to be experimental. Also, Pl share your composition with us for further investigation.
thanks for the suggestion
but I can not see where the error is the x-js
Thanks for the quick response, it is exactly the problem the wrong mime type
have a nice day and happy Benno
