export function getOneSite(body){
    try {
        console.log("getonesite invoked")
    console.log(body)

    return fetch('http://localhost:3001/oneSite',
     {
        method: 'POST',
        headers: {"Content-Type": "application/json"},
        body: JSON.stringify({body}),
        
    })
    .then(data => data.json())
    } catch (error) {
        console.log(error)
    }
    
    
}

this is the funciton im using to make a post request. the swame kind of request works fine in post man but when i try here it give me

Uncaught (in promise) SyntaxError: Unexpected end of JSON input at services.js:12:1

which points towards the request option object but I cant seem to find what about it is wrong.

here is my api end point

app.post('/oneSite', async (req, res)=> {
    console.log(req.body)
    const data = await getOnesite(req.body)

    res.send(data)
})

and here is the mongoose function behind that

async function getOnesite(body) {
    const siteCardData = await siteCardModel.find({_id: body._id}, {_id:0, __v:0}).populate('outages', {'_id':0, '__v':0})
    console.log('getonesite invoked')
    console.log(body)
    console.log(siteCardData[0])
    return siteCardData[0]
}
