This avoids showing an empty-string in an error message which can be quite vexing. The underlying issue which led to this error message was the presence of a ErrorUnused=true with an embedded, squashed struct. This issue is discussed elsewhere, maybe:

#81
#89

This addresses the mystery as discussed in open-telemetry/opentelemetry-collector#13273.
