Request Error

[hmm]

was hab ich hier mit den promise falsch gemacht:

    this.generateOneUpdate = function(email, data) {
        var db = new sqlite3.Database(dbRef);
        var statment = SQL_INSERT_MITARBEITER.replace(/\?name/g, "'" + data.name + "'");
        db.run(statment);
        
        function callback(user_id, m_id, data, dbLokal) {
            var statmentLokal = SQL_INSERT_USER_MITARBEITER.replace(/\?user_id/g, user_id);
            statmentLokal = statmentLokal.replace(/\?m_id/g, m_id);
            dbLokal.run(statmentLokal);
            statmentLokal = SQL_INSERT_SKILL.replace(/\?m_id/g, m_id);
            statmentLokal = statmentLokal.replace(/\?skill/g, "'" + data.skill + "'");
            statmentLokal = statmentLokal.replace(/\?subskill/g, "'" + data.subskill + "'");
            statmentLokal = statmentLokal.replace(/\?nivau/g, "'" + data.nivau + "'");
            dbLokal.run(statmentLokal);
            statmentLokal = SQL_REPLACE_SKILL.replace(/\?m_id/g, m_id);
            statmentLokal = statmentLokal.replace(/\?skill/g, "'" + data.skill + "'");
            statmentLokal = statmentLokal.replace(/\?subskill/g, "'" + data.subskill + "'");
            statmentLokal = statmentLokal.replace(/\?nivau/g, "'" + data.nivau + "'");
            dbLokal.run(statmentLokal);
        }
        
        statment = SQL_SELECT_USER_MITARBEITER_ID.replace(/\?email/g, "'" + email + "'");
        statment = statment.replace(/\?name/g, "'" + data.name + "'");

        var test = new Promise(function(resolve, reject) {db.all(statment, function(err, rows) {
            resolve(rows);
        })});
        
        var pro = function () {
            test.then(function (rows) {
                var dbLokal = new sqlite3.Database(dbRef);
                var last_index = rows.length - 1;
                var user_id = rows[last_index].user_id;
                var m_id = rows[last_index].mitarbeiter_id;
                callback(user_id, m_id, data, dbLokal);
                dbLokal.close();
            })
            .catch(function (error) {
                console.log(error.message);
            });
        }
        
        pro();
        db.close();
    }

ich krieg zwar in dem pro zeugs die daten, aber trotzdem bekomme ich zu 90% eine sqlite_busy: database is locked meldung...
