Description

When using the otlptracehttp exporter to export trace to a custom endpoint, I got error messages despite export succeeded:

2023/02/10 10:34:31 traces export: failed to send to [my own trace agent]: 202 Accepted

/cc @dineshg13

Environment

• OS: MacOS
• Architecture: Apple M1
• Go Version: 1.19
• opentelemetry-go version: v1.13.0

Steps To Reproduce

1. Have a mock backend that returns 202 upon successfully receiving OTLP HTTP trace payloads
2. Run otlptracehttp exporter against the mock backend
3. See error despite traces are successfully exported

Expected behavior

No error logs upon 202 Accepted responses for otlptracehttp exporter.
