Some of the records for the Input Features To Match dataset have invalid geometry or invalid attribute data (or both). Those records (up to the first 30 encountered) are listed. Records that cannot be read will not be included in the analysis.
Examine the Attributes of Interest selected for the analysis to see if there are any NULL values for the target Input Features To Match. Correct the NULL values, remove the attribute with NULL values, or use different target Input Features To Match.
