Hi — just a quick note.
I ran into the same documentation build error on my side, and after digging into it I found that the issue came from the Advanced Alchemy intersphinx mapping still pointing to the old domain. I opened an issue (#4479) and submitted a fix in PR #4480.

This PR (#4477) appears to be failing for the same reason, so once the intersphinx URL is updated, the docs build here should pass as well.

Thanks as always for your help and explanations — really appreciate it.

Just a heads up. We've temporarily reverted the domain swap. I'll bring it back in once we have a way to preserves the old links.

For a deprecation that's scheduled for a removal, this should be pointed at the v2 branch :)

[cofin]

I have some followup changes for this in the main branch that i was making in a followup PR. Can I open another PR once this merges to get this into the v2 branch?

[provinzkraut]

I guess you could merged these into main and then cherry-pick them into v2

Documentation preview will be available shortly at https://litestar-org.github.io/litestar-docs-preview/4477

There's a follow-up PR #4483 that should merge after this one. It should instrument the components that are not instrumented by the ASGI Open Telemetry integration.
