how to format bucket name in AWS for saving - amazon-web-services

Question

Hi i have a lambda function that is trying to save to a bucket:
exports.handler = async (event) => {
console.log('starting');
const { Client } = require('pg');
const client = new Client();
const AWS = require('aws-sdk');
const s3 = new AWS.S3();
var bucketName = 'arn:aws:s3:us-east-1::my_bucket_name';
var keyName = 'prova.txt';
var content = 'This is a sample text file';
var params = { 'Bucket': bucketName, 'Key': keyName, 'Body': content };
try {
console.log('saving...');
const data = await s3.putObject(params).promise();
console.log("Successfully saved object to " + bucketName + "/" + keyName);
} catch (err) {
console.log('err');
console.log(err);
};
But I get the error below. Know what i'm doing wrong?
message: "Access point ARN resource should begin with 'accesspoint/'",
code: 'InvalidAccessPointARN',

Answer 1

Your bucket is not accessible at the moment.
Go to your S3 bucket, then navigate to "Access points" tab.
Create an access point from here.
I believe you need an Internet access point, and to keep things simple, untick the "Block all public access" (not recommended for security).
Once it is created open the access point details and use "Access point ARN" from there.
