Neo4j

thomasf · ‎05-10-2021

Latest Neo4j (4.2.6) and latest APOC (4.2.0.4) on an empty database:

call apoc.import.xml("file:‎⁨/Users/Thomas/Library/Application Support/⁨com.Neo4j.Relate⁩/Data⁩/⁨dbmss⁩/dbms-b0482810-7255-47a0-b994-9228e7bcaa28⁩/import⁩/FODS_Person.xml")

Inevitably leads to:

Failed to invoke procedure apoc.import.xml: Caused by: java.lang.NullPointerException

What have I missed?

thomasf · ‎05-10-2021

Hi again,

I managed to get by this by way of the simple invocation:

call apoc.load.xml("file:///FODS_Person.xml")

I do not know why. And I do think that the punishment that I received yesterday ([Neo.DatabaseError.General.UnknownError]) was too harsh.

Case closed.

Hi Thomas,

I assume you have the following config enabled :
apoc.import.file.enabled=true

By default file paths are relative to the import directory. If you want to use absolute paths, you need to add the following config :
apoc.import.file.use_neo4j_config=false
As your file seems to be in the "import" directory already : call apoc.import.xml("file:///FODS_Person.xml") should also do.

But I'd still expect a "FileNotFound" rather than a "NullPointer", so there may be something else going on. Any stack trace from the log?

Regards,

David

Hi David, and thanks for picking this up. Yes, no and it also works (your 3 suggestions).
I am looking at the debug log right now.
Here are some initial lines from the last session:

The plugins folder contains:

What is wrong here? Why does it try to load all those modules? Cleaning up is maybe what blocks the system?

Or maybe this, which I missed up above, is the problem:

What is a "Client triggered an unexpected error [Neo.DatabaseError.General.UnknownError]"?

thomasf · ‎05-10-2021

I do not believe that there is a column 175 in my input in the desktop browser (stops at 152)

I do not know why. And I do think that the punishment that I received yesterday ([Neo.DatabaseError.General.UnknownError]) was too harsh.

Good to know you're all sorted.

To tie the loose ends, a few comments about the warnings/errors in the log :

WARN [o.n.k.a.p.GlobalProcedures] Failed to load ...

Those are expected APOC warnings : some procedures rely on external jars that are not present in your plugin directory (for example jdbc driver jars would be needed to use the load jdbc procedures).

ERROR [o.n.b.r.s.i.ErrorReporter] Client triggered an unexpected error [Neo.DatabaseError.General.UnknownError]: Lexical error at line 1, column 175. Encountered: after : ""

That's generally just a cypher syntax issue. Maybe a query with unclosed quotes or something of the sort.

Regards,

David
