Error: SRID expected to be either a number or an Integer object but was: undefined

Hello,

I'm having an issue on neo4j spatial point with .transform(XEntity)

Error: SRID expected to be either a number or an Integer object but was: undefined

DEBUG Point { srid: Integer { low: 4326, high: 0 }, x: 50.47511, y: 3.23385, z: undefined }

I will need to check history but I thought point type in Neo4j was supported. This might be a regression. In the meantime you can do what this query does: https://github.com/liberation-data/drivine-inspiration/blob/master/src/movies/moviesForActor-NEO4J.cypher

And unpack the point type into an object with two values, eg:

MATCH (actor:Person {name: $name})
RETURN {
         location:  {lat: actor.location.lat, long: actor.location.lng},
         otherStuff: {name: actor.name} 
       }

If you're interested in sending a PR the code where transformation is done is here:

https://github.com/liberation-data/drivine/blob/master/src/mapper/Neo4jResultMapper.ts

^-- Hmm, yes indeed we can see point should be supported around line 27. Are you doing a read or a write?

@jasperblues thanks for the tip on unpack point.
I found the file, this is where the DEBUG is coming from.

FYI: the error is gone when I deleted :

if (val instanceof neo4j.types.Point) { return val; }
But we're not getting a neo4j point 👎

It's a read query.

Thanks again !

So the desired behavior would be to get some platform agnostic instance of Point ?

By that I mean, instead of return val return new Point(val.lat, val.lng)

Let me also check if any test-cases use the point type. I suspect unfortunately not

Did you get this solved @jclappiway ?

[lefrancoisjc]

I used your solution : unpacking the point manually.
Do you want me to fix this ?

[jasperblues]

Yes pls, if you are happy to @jclappiway !!
