Some EOL Thredds records contain missing metadata. The Thredds harvesting code does not take into account the possibility of missing values, and exceptions are thrown. This may cause dataset records to be entirely ignored instead of being harvested and displayed as containing missing information.

This bug is classified as minor because it involves a small number of dataset records.

Example exceptions from EOL harvesting follow:
