WTForms SelectField停止了提交功能

当我尝试在我的应用程序中添加SelectField时,它将停止应用程序的提交功能,也将停止显示验证警告。当我在添加SelectField之后按下提交按钮时,没有POST请求发送到终端。可能是什么原因造成的?

这里是我的表格:

class AssessForm(FlaskForm):
    date = DateTimeField(label='Review Date', validators=[DataRequired()], default=datetime.now())
    textfield1 = TextAreaField(label='TextField1', validators=[DataRequired()])
    textfield2 = TextAreaField(label='TextField2')
    priority = SelectField(label='Priority', choices=[('low', 'low'), ('medium', 'medium'), ('high', 'high')])
    submit = SubmitField('Submit')

和html:

  <form method="POST" action="">
        {{ form.hidden_tag() }}
        <fieldset class="form-group">
            <legend class="border-bottom mb-4">Join Today</legend>
            <div class="form-group">
                {{ form.date.label(class="form-control-label") }}
                {% if form.date.errors %}
                    {{ form.date(class="form-control form-control-lg is-invalid") }}
                    <div class="invalid-feedback">
                        {% for error in form.date.errors %}
                            <span>{{ error }}</span>
                        {% endfor %}
                    </div>
                {% else %}
                    {{ form.date(class="form-control form-control-lg") }}
                {% endif %}
            </div>
            <div class="form-group">
                {{ form.textfield1.label(class="form-control-label") }}
                {% if form.textfield1.errors %}
                    {{ form.textfield1(class="form-control form-control-lg is-invalid") }}
                    <div class="invalid-feedback">
                        {% for error in form.textfield1.errors %}
                            <span>{{ error }}</span>
                        {% endfor %}
                    </div>
                {% else %}
                    {{ form.textfield1(class="form-control form-control-lg") }}
                {% endif %}
            </div>
            <div class="form-group">
                {{ form.textfield2.label(class="form-control-label") }}
                {% if form.textfield2.errors %}
                    {{ form.textfield2(class="form-control form-control-lg is-invalid") }}
                    <div class="invalid-feedback">
                        {% for error in form.textfield2.errors %}
                            <span>{{ error }}</span>
                        {% endfor %}
                    </div>
                {% else %}
                    {{ form.textfield2(class="form-control form-control-lg") }}
                {% endif %}
            </div>
            <div class="form-group">
                {{ form.priority.label(class="form-control-label") }}
                <form action="" method="post" name="AssessForm">
                    {{form.hidden_tag()}}
                    <p>
                        {{form.priority(size=1)}}
                    </p>
                </form>
            </div>
        </fieldset>
        <div class="form-group">
            {{ form.submit(class="btn btn-outline-info") }}
        </div>
    </form>

如果我删除优先级部分,该表格将按预期工作。
