SNS SDK for NodeJS won't create FIFO topic - node.js

Question

When I create a topic using the sns.createTopic (like the code below) it won't accept the booleans and say 'InvalidParameterType: Expected params.Attributes['FifoTopic'] to be a string', even though the docs say to provide boolean value, and when I provide it with a string of 'true' it still doesn't set the topic type to be FIFO, anyone knows why?
Here's the code:
const TOPIC = {
Name: 'test.fifo',
Attributes: {
FifoTopic: true,
ContentBasedDeduplication: true
},
Tags: [{
Key: 'test-key',
Value: 'test-value'
}]
};
sns.createTopic(TOPIC).promise().then(console.log);

Answer 1

Used aws-sdk V2
I sent FifoTopic and ContentBasedDeduplication as strings.
The below code works fine for me
const TOPIC = {
Name: 'test.fifo',
Attributes: {
FifoTopic: "true",
ContentBasedDeduplication: "true"
},
Tags: [{
Key: 'test-key',
Value: 'test-value'
}]
};
let sns = new AWS.SNS();
let response3 =await sns.createTopic(TOPIC).promise();
console.log(response3);
Note: Make sure your lambda has correct permissions.
You will be getting attributes like FifoTopic and ContentBasedDeduplication when performing the getTopicAttributes.
let respo = await sns.getTopicAttributes({
TopicArn:"arn:aws:sns:us-east-1:XXXXXXX:test.fifo"}
).promise();
