[Error] Unable to use APOC procedures on Colab

[mahimairaja]

I executed the code below:

from llama_index.graph_stores import Neo4jGraphStore

graph_store = Neo4jGraphStore(
    username=username,
    password=password,
    url=url,
    database=database,
)

And, I received the error:

---------------------------------------------------------------------------
ClientError                               Traceback (most recent call last)

     67         try:
---> 68             self.refresh_schema()
     69         except neo4j.exceptions.ClientError:

17 frames
ClientError: {code: Neo.ClientError.Database.DatabaseNotFound} {message: Unable to get a routing table for database 'Instance02' because this database does not exist}

During handling of the above exception, another exception occurred:
