Description
Warnings and errors can occur when loading data into a knowledge graph.
Warnings will not stop the data load process from completing. However, the data may have been loaded into the knowledge graph in an unintended way, or the data is only partially loaded into the knowledge graph. Warnings are common when the data loading configuration file cannot handle some data from the input file. The row in the table where the warning occurs is included. Common data load warnings are as follows:
- The input value could not be converted to the output value for the entity, relationship, or property.
- All null properties prevent import of an entity, relationship, or property in a row.
- Null properties prevent merging of an entity or relationship.
- The input for an entity, relationship, or property could not be read.
Errors will stop the data load process from completing. Errors can occur if the data loading configuration file does not define any entities, relationships, or properties in the input file. Common data load errors are as follows:.
- The load failed.
- The table is empty or was not found.
- The entity type or relationship type could not be created.
Solution
Resolve warnings by verifying that the entity, relationship, or properties are defined correctly in Load Table.
Use the load table settings to prevent warnings and errors related to null properties.
To resolve a failed load, verify that the data loading configuration file is correct for the input data. Create a new data loading configuration that is better suited for the data if necessary.
