Estoy tratando de cargar un archivo e ingresar una tarea de datos en mi MongoDB usando un matraz, pero tuve este error cuando llené mi formulario y cargué la imagen:

Solicitud incorrecta El navegador (o proxy) envió una solicitud que este servidor no pudo entender.

mi código HTML

 <form class="form-check form-control" method="post" enctype="multipart/form-data" action="{{ url_for('index') }}"> <label>Full Name*</label></td> <input name="u_name" type="text" class="text-info my-input" required="required" /> <label>Email*</label> <input name="u_email" type="email" class="text-info my-input" required="required" /> <label>Password*</label> <input name="u_pass" type="password" class="text-info my-input" required="required" /> <label>Your Image*</label> <input name="u_img" type="file" class="text-info" required="required" /></td> <input name="btn_submit" type="submit" class="btn-info" /> </form>

& mi código python:
