What's Wrong?

After upgrade to v1.0.111, Claude Code stop to send out the metrics. Also tested with v1.0.112, v1.0.113

My ~/.claude/settings.json

{
    "env": {
        "CLAUDE_CODE_ENABLE_TELEMETRY": "1",
        "OTEL_METRICS_EXPORTER": "otlp,console",
        "OTEL_LOGS_EXPORTER": "otlp",
        "OTEL_EXPORTER_OTLP_ENDPOINT": "http://alloy.localhost:4317",
        "OTEL_EXPORTER_OTLP_PROTOCOL": "grpc",
        "OTEL_METRIC_EXPORT_INTERVAL": "10000"
    }
}

Downgrade to v1.0.110 could make it work again.

What Should Happen?

Claude Code should have sent out the metrics to OTEL collector and console.

Error Messages/Logs

No error message found

Steps to Reproduce

1. Enable monitoring by adding variables to ~/.claude/settings.json

{
    "env": {
        "CLAUDE_CODE_ENABLE_TELEMETRY": "1",
        "OTEL_METRICS_EXPORTER": "console",
        "OTEL_METRIC_EXPORT_INTERVAL": "10000"
    }
}

1. Open Claude Code and prompt anything
2. Normally we should see some logs on console, but instead there's none.
