nEuler load example data does not work

Load example recipe data in nEuler:

USING PERIODIC COMMIT 1000
LOAD CSV WITH HEADERS FROM "https://github.com/neo4j-apps/neuler/raw/master/sample-data/recipes/recipes.csv"
AS row
MERGE (r:Recipe{name:row.recipe})
WITH r,row.ingredients as ingredients
UNWIND split(ingredients,',') as ingredient
MERGE (i:Ingredient{name:ingredient})
MERGE (r)-[:CONTAINS_INGREDIENT]->(i);

but PERIODIC COMMIT is not supported by Neo4j 4.2.1
Solution: LOAD CSV without PERIODIC COMMIT

Hmm where exactly does that error happen?

When you execute the code as a browser guide? Or from within Neuler?

Do you have a screenshot?

Yes:

The error is not visible in nEuler excplicitly but nEuler does not prodeed and waits forever.

Where exactly? In Desktop / Sandbox ?

If desktop, can you enable "Developer Mode", reload the app and click at the button "Developer Tools" and share the content of the JS console.

If in Browser for Sandbox, please hit F12 to see the JS console.
