My code for the PUT method,

@app.route('/update_doc/<id>', methods=["PUT"])
def update_method(id):
    body = request.get_json()
    updated_document = db_collection.objects.get(id=id).update(**body)
    #document.modify(**body)
    return 'success', 200

I am getting the following error,

 Traceback (most recent call last):

The remaining Post, Delete, Get methods are working. I am giving the input through the postman.

Delete method

@app.route('/stores/<id>', methods=['DELETE'])
def delete_doc(id):
    stores = Store_collection.objects.get(id=id).delete()
    return 'successfully deleted.', 200

通过互联网浏览后，我发现我在我的 MongoDB 数据库中将字段名称指定为“类型”。了解这一点后，我更改了“类型”->“类型”。现在它工作正常。我通过阅读以下 GitHub 问题来理解这一点——> https://github.com/MongoEngine/mongoengine/issues/1194。

此外，同样的问题类似于“大小”这个词。希望这可能对某人有所帮助。
