# AG-UI now sends wire fields to remote entities and exposes streamed errors

> Remote entities now receive wire fields rather than the internal RunContext object, and run errors reach the client over the AG-UI stream instead of disappearing.

We made two fixes to AG-UI's remote and streaming path. We now send wire fields to remote entities instead of the internal `RunContext` object, so what crosses the wire matches the protocol rather than leaking an internal type. We also expose run errors over the AG-UI stream, so a failure during a streamed run reaches the client instead of disappearing.
