Objects are not valid as a React child (again)-CodePudding

I know there is a bunch of the same questions but I really don't understand how to approach this differently than this. I really need an array of objects to be inside a map, I made an array to map it but need to find different info to show so I made a find on array of objects inside the map. How else I can do this other than with objects?!?

I have an array :

itemInfoObjTemp = ["lst_price", "qty_available", "qty_availible_diff"]

and I have an array of objects:

itemInfoObjTemp2 =
    Array [
      Object {
        "field_description": "Javna cijena",
        "id": 2089,
        "name": "lst_price",
      },
      Object {
        "field_description": "Fizička zaliha",
        "id": 3774,
        "name": "qty_available",
      },
      Object {
        "field_description": "Reserved Qty",
        "id": 10970,
        "name": "qty_availible_diff",
      },
    ]

and I'm trying to show the field_description as label, but I'm getting:

Objects are not valid as a React child (found: object with keys {id, field_description, name}). If you meant to render a collection of children, use an array instead.

              {itemInfoObjTemp.map((item, index) => (
                <Text key={index}>
                  <Text style={{ fontWeight: 'bold' }}>
                    {itemInfoObjTemp2.find(item2 =>
                      item2.name === item
                        ? item2.field_description
                        : item
                    )}
                    :
                  </Text>{' '}
                  {itemInfoObj[item].toString()}
                </Text>
              ))}

all this info is dynamic from API, including object properites, so no hardcoding is possible.

Check out the find() docs here.

They state that it "returns the first element in the provided array that satisfies the provided testing function". This means when you call find(), you're receiving an Object back.

Instead, try out something like:

<Text style={{ fontWeight: 'bold' }}>
    {itemInfoObjTemp2.find(item2 => item2.name === item)?.field_description}
</Text>

So I solved it with index:

                  {itemInfoObjTemp.map((item, index) => (
                    <Text key={index}>
                      <Text style={{ fontWeight: 'bold' }}>
                        {itemInfoObjTemp2[index].field_description}:
                      </Text>{' '}
                      {itemInfoObj[item].toString()}
                    </Text>
                  ))}

But this is ridiculous. This will only work if arrays are of the same length and in the right order. In my case they by luck will always, but I really should have other safer options...
