I have this if statement that chooses between two completely different JSON object (displayed below).

I need to display the result on the client side of things, I’m stomped tbh

My goal: I need to be able to display either the error part of the object, or the count part on the page. I’m sure there’s something I’m missing,
My constraints is that I can’t change anything within the JSON files.
Node.js and express related, my background is in basic Java though ;-;

Part of the code I have:

Server side

server.post(etc)
.
.
.
if(!textInputted.text){ 
        result = ({
            error: "Parameter text is missing."
    })} else{
        result = ({
            count: numOfWords
        })
    }
    console.log(result)
    res.json(result)

Client side (it’s just this at the moment, I kept adding and removing)

fetch(etc)
.
.
.
.then (function(res){
              return res.json()
