failed to read request body

Error message

failed to read request body

What it means

Request-body read failure in the audit-log middleware: after PreCheckMetadata matched the request as auditable, io.ReadAll on the request body returned an error (e.g. client aborted mid-upload, connection reset, or an oversized/invalid body). The middleware cannot capture the request content for the audit event, so it aborts with a 500 instead of logging an incomplete audit record.

Solutions

1. Retry the request — transient network interruptions during body upload are a common cause
2. Check for proxy/body-size limits between client and Harbor that could truncate the upload
3. If persistent, capture the underlying read error (server-side) and inspect client connectivity to core
