error handler Unexpected block statement surrounding arrow body

I'm following a node/express course and the instructure has written the below error handler code and I get the error:

Unexpected block statement surrounding arrow body; move the returned value immediately after the =>.eslintarrow-body-style

Any ideas how to fix it?

const catchAsync = fn => {
    return (req, res, next) => {
        fn(req, res, next).catch(next)
    }
}


exports.createTour = catchAsync(async (req, res, next) => {

    const newTour = await Tour.create(req.body);

    res.status(201).json({
        status: 'success',
        data: {
            tour: newTour
        }
    })
})

ref here: https://eslint.org/docs/rules/arrow-body-style

So, Depends on your eslint configuration, it could be

const catchAsync = fn => (req, res, next) => fn(req, res, next).catch(next)

or

// return keyword at nested block
const catchAsync = fn => {
    return (req, res, next) => {
        return fn(req, res, next).catch(next)
    }
}

I guess the fix is the 2nd example
