This isn't all of the files and there are lots more different types of nodes and edges, but this is the format in which I'm importing the files. Any ideas what would throw this exception? I have the --ignore-missing-nodes option enabled so it shouldn't fail the job when I have edges that don't map to nodes -- yet I'm getting a failed job as a result of the posted error. ---

Did you read the docs? [https://neo4j.com/docs/operations-manual/current/tools/import/file-header-format/](https://neo4j.com/docs/operations-manual/current/tools/import/file-header-format/) Your nodes need at least one `:ID` field and your relationships need at least one `:START_ID` and `:END_ID` header field each.
