Unable to store value in DB

I’m having trouble storing a value in the DB. Now it should be said, that I’ve saved something else under a separate key to the DB, and that worked fine; But for some reason, the function below just doesn’t get saved (I iterate over the keys to check if it exists, it’s never created).

func (m *Model) Save() error {
	if m.context == editProject {
		m.ProjectData.Name = m.projectForm.projectName.Value()
		m.ProjectData.ContactName = m.projectForm.contactName.Value()
		m.ProjectData.FaName = m.projectForm.faName.Value()

	db, err := badger.Open(badger.DefaultOptions("./data"))
	if err != nil {
		logger.Errorf("Unable to open database.")
		return err
	defer db.Close()

	// Since Badgerdb is a k/v store, we need to consider how we store
	// structured data. So we use a identifiable key prefix "projects."
	dbKey := fmt.Sprintf("project_%s\n", m.ProjectData.FaName)

	// Save the project data
	err = db.Update(func(txn *badger.Txn) error {
		data, err := json.Marshal(&m.ProjectData)
		if err = txn.Set([]byte(dbKey), data); err != nil {
			fmt.Printf("Json Data: %s\n", data)
			fmt.Printf("DB Set Error? %s\n", err)
			return err
		return nil

	// return err
	return nil

I’m new to Badger, and find it confusing why a different function, with a slightly different JSON structure (but still json) is saved, but the function above does not.

Ok, apologies, i was mistaken. The data was indeed being stored, my method for reading the keys back had typo in the prefix, silly mistake.
