Hello, in certification question, upload csv to neo4j sandox I did all tasks, ran queries and received confirmation, that data are uploaded. It confirmed.
In the sandbox pane confirmed 1097 nodes: MATCH (n) RETURN count(n)
It confirmed 4065 nodes:
MATCH ()-[r]->() RETURN count(r)
But the validator says it was not correct, over the fact it is.
I *think* I have found the reason for the verification failure that is occurring for me at least. I re-ran the import using the "solution mapping file" at https://data.neo4j.com/importing/movieModel-solution.json and the verification passed, Then I compared this mapping file with the non-working mapping file that I had previously downloaded.
What I found was that when I carried out the mapping exercise, all the ID fields where interpreted by the importer as Integer type, whereas in the working solution file they are all string type.
I can find no mention in the instructions to set the type for these fields to string; but of course I cannot verify this as the fix as I now cannot reset the lesson to test my theory
