Pull request overview
This PR fixes deferred export functionality by correcting how OTLP headers are formatted before being passed to curl. The issue was that headers were being written to a file in their raw environment variable format (comma-separated key=value pairs) rather than in the format curl expects (one header per line with "key: value" format).
Changes:
- Removed the initial blanket write of
$OTEL_EXPORTER_OTLP_HEADERSto the headers file - Updated header processing for logs, metrics, and traces to properly combine and format headers using
tr,grep, andsedto convert from comma-separatedkey=valueformat to line-separatedkey: valueformat
