I called s3 api by copyObject. But, i got the 403 error for access denied.

I have configured it as follows.

IAM + CORS settings

IAM is S3FullAccess.

CORS is allowed.

[
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "PUT",
            "POST",
            "DELETE"
        ],
        "AllowedOrigins": [
            "http://localhost:3002"
        ],
        "ExposeHeaders": []
    }
]

I don't know what I am missing.

code:

import AWS from 'aws-sdk';

AWS.config.update({
  accessKeyId: process.env.NEXT_PUBLIC_AWS_ACCESS_KEY_ID,
  secretAccessKey: process.env.NEXT_PUBLIC_AWS_SECRET_ACCESS_KEY,
})

bucket = new AWS.S3({
  params: { Bucket: 'bucket' },
  region: 'ap-northeast-2',
});

const params = {
  Bucket: 'bucket',
  CopySource: `advertisement_${i}.png`,
  Key: `advertisement_${i}_old.png`,
};

await this.bucket.copyObject(params)
  .send((err => {
    if (err) {
      alert(err);
    } else {
      console.log(`advertisement_${i} is copied`);
    }
  }));
