Json results being duplicated from simple query

GSQL
#1

I have a simple query that displays 4 vertices as expected, but when I look at the Json output the 4 vertices are represented twice. This is the query:

Start = {inputConcept};
Items = SELECT t FROM Start:s-(Concept_Has_ConceptItem>:e)-ConceptItem:t;
PRINT Items;

and this is the output:

and this is the Json:

[
{
“Items”: [
{
“v_id”: “11”,
“v_type”: “ConceptItem”,
“attributes”: {
“name”: “OnePlus 8 Pro”,
“description”: “”,
“Id”: 11
}
},
{
“v_id”: “8”,
“v_type”: “ConceptItem”,
“attributes”: {
“name”: “iPhone 11 Pro”,
“description”: “”,
“Id”: 8
}
},
{
“v_id”: “10”,
“v_type”: “ConceptItem”,
“attributes”: {
“name”: “Google Pixel 4”,
“description”: “”,
“Id”: 10
}
},
{
“v_id”: “9”,
“v_type”: “ConceptItem”,
“attributes”: {
“name”: “Samsung Galaxy S20”,
“description”: “”,
“Id”: 9
}
}
]
},
{
“Items”: [
{
“v_id”: “11”,
“v_type”: “ConceptItem”,
“attributes”: {
“name”: “OnePlus 8 Pro”,
“description”: “”,
“Id”: 11
}
},
{
“v_id”: “10”,
“v_type”: “ConceptItem”,
“attributes”: {
“name”: “Google Pixel 4”,
“description”: “”,
“Id”: 10
}
},
{
“v_id”: “8”,
“v_type”: “ConceptItem”,
“attributes”: {
“name”: “iPhone 11 Pro”,
“description”: “”,
“Id”: 8
}
},
{
“v_id”: “9”,
“v_type”: “ConceptItem”,
“attributes”: {
“name”: “Samsung Galaxy S20”,
“description”: “”,
“Id”: 9
}
}
]
}
]

Can someone please explain why the Json is duplicated?

Thank you.

That looks odd.
Can you give us the schema too and I’ll try it out?

Thanks rik,

Having to replace all INT primary IDs with STRING (guid) data types forced me to drop and rebuild everything in the graph. Now when I execute the same query with the new vertices and edges it works as expected and there’s no way to determine what happened.

I guess this is a good problem.

Okay, good, I think :slight_smile: Hopefully it never returns. If it does. Please let us know.
