Save result of promises inside an array with async/await

I'm writing a script that should count elements in a JSON file. I can't figure out how to save results of promises in an array.

This is the async function that counts the elements:

async function countVulnerabilities(dir, project, branch) {
    await count[dir](new URL(path.join('/dropbox/sast/', project, branch, dir), process.env.REMOTE_DRIVE_PATH))
        .then((result) => {
            return result
        })
}

The function that calls it is this:

export function getLogs(req, res, id, project, branch) {
    let count = []
    if (checkMappedDrive()) {
        getDirs(project, branch)
            .then((dirs) => {
                dirs.forEach((dir) =>  {
                    countVulnerabilities(dir, project, branch)
                    .then((result) => {
                        count.push(result)
                        console.log(result)
                    })
                })
            })
            res.send(count)
    } else {
        res.send('Impossible to enstablish a connection with the remote drive')
    }
}

How can I push results in the count array? At the moment, it's returning [].

Many thanks

async function countVulnerabilities(dir, project, branch) {
    return await count[dir](new URL(path.join('/dropbox/sast/', project, branch, dir), process.env.REMOTE_DRIVE_PATH))
}

what is count in this function?
