Node.js 无服务器无法获取所有记录事件对象验证失败

我正在try 使用query和JSON模式获取所有记录，但我一直得到Event object failed validation条记录，除非我通过了一个查询，它没有给我任何结果.

这个案子用了@middy/validator个任何人都已经2天了我还是不知道问题出在哪里

JSON模式文件

const getAuctionsSchema = {
    type: 'object',
    required: ['queryStringParameters'],
    properties: {
        queryStringParameters: {
            type: 'object',
            required: ['status'],
            properties: {
                status: {
                    default: 'OPEN',
                    enum: ['OPEN', 'CLOSED'],
                },
            },
        },
    },
};

module.exports = getAuctionsSchema;

这里是所有记录获取文件

const AWS = require('aws-sdk');
const createError = require('http-errors');
const validator = require('@middy/validator');
const commonMiddleware = require('../lib/commonMiddleware');
const getAuctionsSchema = require('../lib/schemas/getAuctionsSchema');

const dynamoDB = new AWS.DynamoDB.DocumentClient();

const get_auctions = async (event) => {
    const { status } = event.queryStringParameters;
    let auctions;

    const params = {
        TableName: process.env.AUCTIONS_TABLE_NAME,
        IndexName: 'statusAndEndDate',
        KeyConditionExpression: '#status = :status',
        ExpressionAttributeValues: {
            ':status': status,
        },
        ExpressionAttributeNames: {
            '#status': 'status',
        },
    };

    try {
        const result = await dynamoDB.query(params).promise();

        auctions = result.Items;
    } catch (err) {
        console.log(err);
        throw new createError.InternalServerError(err);
    }

    return {
        statusCode: 200,
        body: JSON.stringify(auctions),
    };
};

module.exports = {
    handler: commonMiddleware(get_auctions).use(
        validator({
            inputSchema: getAuctionsSchema,
            ajvOptions: {
                useDefaults: true,
                strict: false,
            },
        })
    ),
};

以下是我在Cloud Watch中看到的错误
