I try to import data into a Neo4j VM in Azure.

This code works:

def create_article(tx):
    tx.run("CREATE (a:ARTICLE)")

session.read_transaction(create_article)

But this code doesn't work:

def create_node_article(tx, id, title, label):
    tx.run("CREATE (a:ARTICLE {id:$id, title:$title, label:$label})", id=id, title=title, label=label)

for index, row in df_article_ids.iterrows():
    session.read_transaction(create_node_article, row['id'], row['cleaned_best_title'], row['label'])

I have the error:

Transaction failed and will be retried in 1.0608892687544587s (Failed to read from defunct connection Address(host='IP', port=7687) (Address(host='IP', port=7687)))

I don't know what I have to change or check. I also tried Neo4j Desktop and I have the same error.

Neo4j version: 4.1.3

You are using a read_transaction when in reality you are updating the database. Try the write_transaction – Tomaž Bratanič Nov 13 '20 at 17:38
Thank you, can also it be a conflict between the version of the python driver and the neo4j version ? – LJRB Nov 13 '20 at 18:09
