Need advise on error "mismatched data points" in Span Metrics Connector

[rahjesh-vunet]

I am getting the below error in the Span Metrics Connector.

exporterhelper/queued_retry.go:391 Exporting failed. The error is not retryable. Dropping data.
{"kind": "exporter", "data_type": "metrics", "name": "kafka/metrics", "error": "Permanent error: mismatched data points: calls=0, duration=2","dropped_items": 1232}

Any idea on this?
