英文:
Dynamodb query returns json with synthax error
问题
以下是您的代码的翻译：
let ddb = new AWS.DynamoDB(config)
export const dynamoDb = ddb
export const dynamoClient = new AWS.DynamoDB.DocumentClient({
service: dynamoDb
})
let params = {
TableName: auditTable,
IndexName: 'importId-auditStatus-index',
KeyConditionExpression: 'importId = :importId and auditStatus = :auditStatus',
ExpressionAttributeValues: {
':importId': importId,
':auditStatus': 'Imported'
}
}
let response = await dynamoClient.query(params, function(err, data) {
if (err) {
console.log("Error", err);
} else {
return data;
}
}).promise();
console.log("response",response)
JSON 数据部分没有发生语法错误。如果您有特定的问题或者需要帮助，请随时告诉我。

你分享的代码和输出不对齐。代码中使用的文档客户端 dynamoClient 返回本机 JSON。代码中的低级客户端 dynamoDb 和 ddb 将返回 DynamoDB JSON，这是您输出并称之为语法错误的内容。
英文:
The code you're sharing and the output you shared are not aligned. The Document Client dynamoClient which you use in the code returns native JSON. The low level client dynamoDb and ddb in your code will return DynamoDB JSON, which is what you are outputting and calling a syntax error.
