Hi guys, how you guys are doing? I hope everything is fine =)
I'm starting to work with aws-sdk-js, but I think I have some limitation in my knowledge of typescript,
I was trying to get the response data from the support.describeTrustedAdvisorChecks in such a way
try{
const response = await support.describeTrustedAdvisorChecks({language: 'en'})
}and it wasn't working, so I decided to take a look on the typescript implementation
describeTrustedAdvisorChecks(callback?: (err: AWSError, data: Support.Types.DescribeTrustedAdvisorChecksResponse) => void): Request<Support.Types.DescribeTrustedAdvisorChecksResponse, AWSError>;I'm really not sure but I think that I won't be able to get the data out of the describeTrustedAdvisorChecks method, unless I pass a callback and work with that data inside of it, is that right?
So using async await won't help me in that case right? =(
Hi Guys, understand this question may have been answered - looking for some idea. I have a lambda update function which just updates a row in a table. I am keeping the primary key -id as event.id and using the PUT method . When I test the function through Lambda, it works fine and updates the DynamoDB table. When I test from AWS API gateway, it gives error of attribute not initialised " "errorType": "ValidationException",
"errorMessage": "Supplied AttributeValue is empty, must contain exactly one of the supported datatypes". I am passing the id as path variable. and the logs look like the function is taking the path and the body attributes. as below Mon Jun 01 07:31:41 UTC 2020 : Method request path: {id=4aaf78ea-4d7a-49d5-b2bb-0c7ad1137495}
Mon Jun 01 07:31:41 UTC 2020 : Method request query string: {}
Mon Jun 01 07:31:41 UTC 2020 : Method request headers: {}
Mon Jun 01 07:31:41 UTC 2020 : Method request body before transformations: {
"cover":"XXXX",
"productType":"GGGG",
"state":"TAS",
"value":"4000"
} My Lambda function is as follows: const AWS = require("aws-sdk");
const dynamodb = new AWS.DynamoDB({
region: "ap-southeast-2",
apiVersion: "2012-08-10"
});
exports.handler = (event, context, callback) => {
const params = {
Item: {
id: {
S: event.id
},
cover: {
S: event.cover
},
productType: {
S: event.productType
},
state: {
S: event.state
},
value: {
S: event.value
}
},
TableName: "testtable" };
dynamodb.putItem(params, (err, data) => {
if (err) {
console.log(err);
callback(err);
} else {
callback(null, {
id: params.Item.id.S,
cover: params.Item.cover.S,
productType: params.Item.productType.S,
state: params.Item.state.S,
value: params.Item.value.S
});
}
});
};
event.pathParameters.id. then what you are trying to provide as state, value, cover... are probably stored in the body of your request, event.body. Be aware that it is a stringified value so you will need JSON.parse(event.body).productType to get the productType for instance
Thanks, I changed the code of the handler function as below but I am still getting error as id is undefined.
exports.handler = (event, context, callback) => {
const id = event.pathParameters.id;
const reqBody = JSON.parse(event.body);
const { cover,productType,state,value} = reqBody;
const params = {
Key: {
id: id
},
TableName: "baserate",
ConditionExpression: 'attribute_exists(id)',
UpdateExpression: 'SET cover = :cover, productType = :productType,state = :state,value = :value',
ExpressionAttributeValues: {
':cover': cover,
':productType': productType,
':state': state,
':value': value
},
ReturnValues: 'ALL_NEW'
};{

});i am facing an error :
