Flask表单提交后调用Discord Webhook触发400 Bad Request错误的问题求助

大家好，我现在遇到个头疼的问题：我用Flask做了个网站，里面有个提交工作记录的表单，本来预期是用户填完信息提交后，Flask把数据整理成Discord Embed，通过Webhook发送到指定频道，但现在每次提交都会触发requests.exceptions.HTTPError: 400 Client Error: Bad Request for url:错误。我折腾快一小时了，Python水平大概入门到进阶之间，实在找不到问题在哪，想请大家帮忙看看。

我试过的解决办法 #

• 给Webhook发送代码加了try, except块捕获异常，但还是没定位到具体原因
• 把表单里的日期输入转成了字符串类型，避免格式问题
• 用同一个Webhook测试过其他简单的Embed内容，是能正常发送的，说明Webhook本身没问题

预期的正常流程 #

用户填完表单里的必填项（还有可选的游戏复选框），点击提交按钮后，Flask接收表单数据，生成对应的Discord Embed，通过Webhook发送到指定的Discord频道。
