node.js - Javascript Promise never gets resolved

Question

I′m trying to read a file and register its hash to a database, after checking if these file already doesn`t exist. For that I have to use a aync function, like this:

async function createHashAndStore(err, data) {
          if (err) {
            console.log(`err ${err}`)
          }
          const hashFile = sha256(data.toString('utf8')).toString()
          const afData = new AfData()
          try {
            const createAfData = afData
              .checkIfFileAlreadyExist(hashFile)
              .then((exists) => {
                if (!exists) {
                  afData
                    .store({ hash: hashFile, send_date: new Date() })
                    .then((response) => console.log(response))
                    .catch((err) => console.log(err))
                  return true
                } else {
                  return false
                }
              })
              .catch((err) => console.log(err))
            console.log(`createAfData ${await createAfData}`)
            return await createAfData
          } catch (err) {
            console.log(err)
          }
        }

        const readFileAsync = util.promisify(fs.readFile)

        const readFileAndStore = () => readFileAsync(
          Helpers.tmpPath('uploads/' + fileName),
          'utf8',
          createHashAndStore
        )
