redisgraph-bulk-loader returns with IndexError

I am trying to use the redisgraph-bulk-loader to load the dataset into the RedisGraph instance running in a docker container. However, it returns with IndexError: list index out of range which I do not understand. I have read the documentation and my CSV files are valid.

I have opened an issue here.

Command : $ redisgraph-bulk-loader DemoGraph --enforce-schema --nodes-with-label TBox import/nodes.csv --relations-with-type relations import/relationships.csv

Solution

The error you're encountering occurs at this line - https://github.com/RedisGraph/redisgraph-bulk-loader/blob/master/redisgraph_bulk_loader/entity_file.py#L233 .

At this point, we are trying to retrieve the type specified after the colon in a specific field of a header line. As such, an IndexError indicates that no colon was found in one of the fields.

Looking at relationship.csv, I see that the header row ends with "properties__title","properties__uri","end__labels__002". These columns should have a colon-separated type, like the preceding fields.
