Adding objects from string input via Typescript function

[robind]

Passing in a dictionary as a string from AIP Logic into Typescript function. Trying to add the objects to the object type, but struggling. This is my code:

import { Function } from "@foundry/functions-api";
import {DeliveryNote } from "@foundry/ontology-api";


export class DeliveryTest {

    @Function()
    public addDeliveryNoteObjects(existingObjects: DeliveryNote[], deliveryString: string): DeliveryNote[] {
        const delivery = JSON.parse(deliveryString);

        const newObjects: DeliveryNote[] = delivery.Materials.map((item: any, index: number) => {
            return {
                primaryKey_: (existingObjects.length + index + 1).toString(),
                company: delivery.Company,
                deliveryDate: delivery["Delivery Date"],
                deliveryInfo: delivery["Delivery Info"],
                material: item.Name,
                quantity: item.Quantity
            };
        });

        console.log('New Objects:', newObjects);
        return existingObjects.concat(newObjects);
    }
}

when I use this example (just one material for simplicity):

{“Company”: “ABC”,“Delivery Date”:“November 7, 2024”,“Delivery Info”: “Materials for xyz.”,“Materials”:[{“Name”:“12-inch PVC Pipes”,“Quantity”:“100 units” }]}

I get this:

Found unexpected value for function return type.
Error Parameters: {
“value”: “{"primaryKey_":"1","company":"ABC","deliveryDate":"November 7, 2024","deliveryInfo":"Materials for xyz.","material":"12-inch PVC Pipes","quantity":"100 units"}”,
“returnType”: “object”
}

at Object.visit (FunctionsIsolateRuntimePackage:2:645415)

and log output is

LOG [2025-04-01T10:18:47.651Z] New Objects: [ { primaryKey_: ‘1’,
company: ‘ABC’,
deliveryDate: ‘November 7, 2024’,
deliveryInfo: ‘Materials for xyz.’,
material: ‘12-inch PVC Pipes’,
quantity: ‘100 units’ } ]

The new object seems ok but something is not happy re adding the object to ontology…

Ah, I was on the wrong track, I just had to iterate through the dictionary and create an object during every loop.

import { OntologyEditFunction, Edits } from "@foundry/functions-api";
import { DeliveryNote, Objects } from "@foundry/ontology-api";

export class addDeliveryNoteFunction {
    @Edits(DeliveryNote)
    @OntologyEditFunction()
    public addDeliveryNoteObjects(deliveryString: string): void {
        const delivery = JSON.parse(deliveryString);
        const timestamp = Date.now().toString();
        let i = 1;

        delivery.Materials.forEach((item: any, index: number) => {
            const newObj = Objects.create().deliveryNote(timestamp + "_" + i.toString());
            newObj.company = delivery.Company;
            newObj.deliveryDate = delivery["Delivery Date"];
            newObj.deliveryInfo = delivery["Delivery Info"];
            newObj.material = item.Name;
            newObj.quantity = item.Quantity;
            i += 1;
        });
    }
}

This works:

{
“Company”: “ACME piping”,
“Delivery Date”: “November 7, 2024”,
“Delivery Info”: “Materials for construction at Pittsburgh Project Site.”,
“Materials”: [
{ “Name”: “12-inch PVC Pipes”, “Quantity”: “100 units” },
{ “Name”: “Cement Bags”, “Quantity”: “50 bags” },
{ “Name”: “Steel Reinforcement Bars”, “Quantity”: “200 rods” }
]
}
