DB. Browser.Sqlite.OperationalError: database is locked

Question

我正在尝试将表单提交到 DB Browser Sqlite。我创建了一个 table。我能够将数据存储到 Sqlite 中。但是，一旦我添加了一个函数来在提交按钮 (submitclaim.html) 中执行一个确认弹出框，我就显示了这个错误

sqlite3.OperationalError: database is locked

当我尝试向 table 提交表单时，它发生在以下行：

    c.execute("INSERT INTO SubmitClaim VALUES (?,?,?,?,?)", (depart, type, uploadre, amt, description)

这是我的app.py

@app.route('/addrec', methods=['POST', 'GET'])
def addrec():
    if request.method == 'POST':

        depart = request.form['depart']
        type = request.form['type']
        uploadre = request.form['uploadre']

        amt = request.form['amt']
        description = request.form['description']

    conn = sql.connect(db_path)
    c = conn.cursor()

    c.execute(
        "INSERT INTO SubmitClaim VALUES (?,?,?,?,?)", (depart, type, uploadre, amt, description))

    conn.commit()

    c.execute("SELECT * FROM  SubmitClaim")
    print(c.fetchall())
    conn.close()

    return render_template('base.html', user=session["user"], version=msal.__version__)

这是我的SubmitClaim.html

<div class="arrange3">
    <button onclick="myFunction()" type="submit" class="submit-button" name="save", value="save">Submit</button>
    <script>
    function myFunction() {
    confirm("Press a button!");
    }
