Describe the bug When I upload file and try to create kg. After processing the file in container logs following error appers:

2024-08-27T09:10:36.447361443Z WARNING:neo4j.notifications:Received notification from DBMS server: {severity: WARNING} {code: Neo.ClientNotification.Statement.UnknownPropertyKeyWarning} {category: UNRECOGNIZED} {title: The provided property key is not in the database} {description: One of the property names in your query is not available in the database, make sure you didn't misspell it or that the label is available when you run this statement in your application (the missing property name is: name)} {position: line: 3, column: 86, offset: 107} for query: '\n MATCH (n1)-[r]->(n2)\n return n1.name AS subject, n1.description AS subject_description, n2.name AS object, n2.description AS object_description, type(r) AS relation, r.description AS relation_description\n SKIP 0\n LIMIT 100\n '

and output of r2r inspect-knowledge-graph:

Hey, could you check if your r2r version/docker containers are up to date? Also, it is recommended that you start your server using the following command.

r2r serve --docker --config-name=neo4j_kg

You should be able to do

r2r ingest-sample-file
r2r enrich-graph
r2r inspect-knowledge-graph

And finally, then try with your custom file

Let me know if this doesn't work. Thanks!

The problem is I cannot start like that. I am doing it in air gapped servers. I am using a repository that caches other docker images. Then I need to change docker images. I tried as you said:

r2r ingest-sample-file
r2r inspect-knowledge-graph

I have the same error. I started from neo4j_kg config as you mentioned.
