Hi @shahzad31, I'm on support & the UX page doesn't load without those fields 😉

I directed Robbert here because that seems to be a RUM-API config problem cascading. With your feedback, it sounds like we're thinking it's a bug for the RUM-API, so my apologies for redirecting. I'm consolidating history & will escalate to Dev tagging you so you have the full picture (this + private data).

After, we can share the TLDR resolution path for people googling this thread!

Ok, update for everyone: it looks like the v3 data mapping has a bug which already has a PR up for review:

- [[bug] transaction marks mapping is incorrect for v3 API · Issue #1007 · elastic/apm-agent-rum-js · GitHub](https://github.com/elastic/apm-agent-rum-js/issues/1007)
- [fix(rum-core): mapping for marks were incorrect by vigneshshanmugam · Pull Request #1008 · elastic/apm-agent-rum-js · GitHub](https://github.com/elastic/apm-agent-rum-js/pull/1008)
