Some of the records for the Candidate Features dataset have invalid geometry, 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 Candidate Features. Correct the NULL values, remove the attributes containing NULL values, or remove the Candidate Features with NULL values for any of the Attributes of Interest.
