ListObjects request from Salesforce to AWS S3 results in "refused to connect" error

Question

I'm developing a Salesforce component that makes a request to AWS S3 using the AWS JavaScript SDK.

When making the request below, I receive the console error Refused to connect to https://mybucket.s3.amazonaws.com/list-type=2&prefix=00Q5e000001Vx7iEAC

s3.listObjectsV2(
  {Bucket:'mybucket', Prefix: component.get('v.recordId')},
  function (err, data) {
    if (err) {
      console.log(err);
    } else {
      console.log(data);
    }
  }
);

I am confused why this is happening since I am able to make requests using s3.getSignedUrl() without any errors.

What do I need to do to allow this request from Salesforce to AWS?

Answer 1

As @jellycsc said, I realized that the requests were different.

Turns out that I just needed to add https://mybucket.s3.amazonaws.com to my CSP trusted sites in Salesforce.
