What
OTEL_RESOURCE_ATTRIBUTES is an environment variable that adds labels to the OpenTelemetry data (usage and performance data) Claude Code can send. Claude Code now checks each entry and drops any that is broken, showing a warning on the /status screen. An entry is broken when it has:
no =
an extra =
an empty key
invalid percent-encoding
too much text
Entries that would leave the labels off metric points, events and spans get a separate notice. After fixing an entry, restart Claude Code, because these labels are only read at startup.
Why
Mistakes in this setting used to fail silently, and now you can see which entries were left out and why.
