Express.js application bug: Cannot read property 'transfer-encoding' of undefined
问题 I am working on a blogging application (click the link to see the GitHub repo) with Express, EJS and MongoDB. I am trying to introduce an add post image feature. Being quite new to Express, I am puzzled about the problem I have ran into. The add post form: <form action="/dashboard/post/add" method="POST" enctype="multipart/form-data" class="mb-0"> <div class="form-group"> <input type="text" class="form-control" name="title" value="<%= typeof form!='undefined' ? form.titleholder : '' %>"
