Sqlite Database is cleared on redeployment

Hi i’ve mounted a sqlite database to the volume via the database url env DATABASE_URL=sqlite3:///mnt/volumename/production.sqlite but whenever i deploy the database is is mounted in the app/path to db folder instead of mnt/path to db. Therefore on any redeployment the data is wiped.

its a small Nodejs app with sequelize as the orm. My build and start script is

"build": "rimraf ./build  && tsc",
"start": "yarn run build && yarn db:migrate:prod && node ./build/index.js",

fly.toml looks like this

app = "app name"
kill_signal = "SIGINT"
kill_timeout = 5
processes = []

[env]
  PORT = "8080"

[experimental]
  allowed_public_ports = []
  auto_rollback = true

[mounts]
  source="nameofvolume"
  destination="/mnt/nameofvolume"

[[services]]
  http_checks = []
  internal_port = 8080
  processes = ["app"]
  protocol = "tcp"
  script_checks = []
  [services.concurrency]
    hard_limit = 25
    soft_limit = 20
    type = "connections"

  [[services.ports]]
    force_https = true
    handlers = ["http"]
    port = 80

  [[services.ports]]
    handlers = ["tls", "http"]
    port = 443

  [[services.tcp_checks]]
    grace_period = "1s"
    interval = "15s"
    restart_limit = 0
    timeout = "2s"

I need the database to remain regardless of deployment. How can i go about this.
