fix(livekit-agents): require livekit-protocol>=1.1.21 for MetricsRecordingHeader.simulated#6541
Merged
Conversation
…rdingHeader.simulated #6497 writes MetricsRecordingHeader.simulated / redaction_enabled in the session-report upload, but left the dependency floor at livekit-protocol>=1.1.19, which predates those proto fields (added in 1.1.21). A non-locked install resolving to the floor crashes the entire session-report upload with 'MetricsRecordingHeader has no "simulated" field', dropping the recorded chat history. Bump the floor to the first release that defines them.

Why
#6497 added simulation/redaction telemetry tagging:
telemetry/traces.pynow buildsMetricsRecordingHeader(..., simulated=..., redaction_enabled=...)in the session-report upload. But it left the dependency floor atlivekit-protocol>=1.1.19,<2, and those proto fields were only added inlivekit-protocol1.1.21 (proto side of livekit/protocol#1679; Go equivalent shipped inv1.50.4).As a result, any install that resolves
livekit-protocolto the floor (1.1.19 or 1.1.20 — non-locked installs, e.g.pip install livekit-agents) crashes on every session-report upload:Because the upload fails, the recorded
chat_historyis never stored, which in turn makes the simulation summarizer 404-loop fetching it.What
livekit-protocolfloor to>=1.1.21,<2— the first release that definesMetricsRecordingHeader.simulated/redaction_enabled— so the declared dependency actually guarantees the fields feat: tag simulation and redaction telemetry #6497 writes.uv lock): the resolved version was already 1.1.21, so this is a one-line specifier update with no package churn.Verified
With
livekit-protocol==1.1.21installed, alk agent simulaterun uploads the session report cleanly (uploading session report→finished uploading) and the exported run JSON retains fullfunction_call.argumentsandfunction_call_output.output(redaction is skipped for simulation sessions).
