该应用程序基于flask和bootstrap 3.我有一个带有选项的模态（data-backdrop =“static”，data-keyboard =“false”），以防止用户点击或使用转义时关闭它键。点击被忽略，但是转义键导致烧瓶应用程序崩溃，并带有指示管道损坏的回溯。
我相信HTML是正确的。我不确定为什么忽略bootstrap模态选项以及为什么烧瓶应用程序崩溃。
HTML：
<div class="modal fade" role="dialog" id="working-modal"
data-backdrop="static" data-keyboard="false">
<div class="modal-dialog modal-sm" role="document">
<div class="modal-content">
<div class="modal-body">
<h4 class="modal-title text-center">Working</h4>
</div>
</div>
</div>
</div>
