agent: observability

When does this happen?

IF OpenTelemetry exporter receives HTTP 204 on POST /v1/traces instead of expected 200, logging 'Failed to export batch code: 204, reason:'.

How others solved it

THEN Upgrade Phoenix to a version that includes fix #5962, which changes the response status from 204 to 200 for the POST /v1/traces endpoint. Verify your deployment uses a Phoenix version with this fix to comply with the OTLP specification and prevent export failures.
