I'm using the neo4j-advanced-rag LangChain template (neo4j-advanced-rag | 🦜️🔗 Langchain). I followed exactly the steps described in the documentation. In my app I set the correct NEO4J_URI, NEO4J_USERNAME and NEO4J_PASSWORD.
The AuraDB neo4j is up and running, I can explore data and make queries using the browser interface.
Despite this, I get the following error when starting langchain serve
:
ValueError: Could not connect to Neo4j database. Please ensure that the url is correct
How could I solve this problem?
