我有一個燒瓶應用程序，當用戶單擊索引頁面上的按鈕時，它們會觸發(fā)生成報告，并使用 send_file() 函數(shù)將其下載到瀏覽器中。每次創(chuàng)建和下載報告時，服務器都會停止，我在終端中收到以下錯誤。每次都需要重新啟動，我不知道如何修復它。有任何想法嗎？:)flask_app.py 文件：from flask import Flask, render_template, request, url_for, flashimport create_reportfrom flask_debugtoolbar import DebugToolbarExtensionfrom flask import send_fileapp = Flask(__name__)filename = ""@app.route("/")def index():    return render_template("index.html")@app.route("/handle_data", methods=['GET', 'POST'])def handle_data():    text = request.form['accountinput']    preprocessed_text = text.lower()    filename = create_report.start_script(preprocessed_text)    path = "reports/" + filename    return send_file(path, as_attachment=True)if __name__ == '__main__':    app.run(debug=True)終端錯誤：Assertion failed: (NSViewIsCurrentlyBuildingLayerTreeForDisplay() != currentlyBuildingLayerTree), function NSViewSetCurrentlyBuildingLayerTreeForDisplay, file /BuildRoot/Library/Caches/com.apple.xbs/Sources/AppKit/AppKit-1561.60.100/AppKit.subproj/NSView.m, line 14485.
