The open source ethos of ethereum and farcaster makes building frames so much easier. Even in just a few days, so many github repos to review implementations of and documentation shared by users.

All those 500 errors you are seeing are due to missing `post_url` header value from the next frame response you are sending. (Again not an issue on actual casts, only on embed dev tools)

When I cast the URL you shared I am seeing animated content appear as a response. Is there something else that is suppose to show?

If the embed tool is showing internal errors for your POSTs, check if post_url is missing
