When does this happen?

IF POST /v1/traces returns HTTP 204 instead of 200, causing OTel Python exporter to log 'Failed to export batch' with code 204.

How others solved it

THEN Upgrade Phoenix to a version that includes the fix from PR #5962, which changes the response status for POST /v1/traces from 204 to 200 as required by the OTLP specification.
