Improper use of relationship types

Be sure to build your edges with meaningful relationship types. Do not use a single, general type such as CONNECTED_TO for different types of relationships.^[1] Be specific. On the other end of that spectrum, it is also important not to make every relationship unique. Neo4j caps the number of relationship types at 65,000, and your model should not approach that number. Following either of those extremes will create trouble later with queries that traverse relationships. Problems with relationship type usage usually stem from a lack of understanding of the property graph model.
