@FlyingTurkman are you utilizing the documentation here? Does the application have auth resource configured?

transferring to Amplify JS repository for further assistance.

Hi @FlyingTurkman is this issue happening locally or after you deploy to hosting?

[FlyingTurkman]

@nadetastic I figure it out. Problem was about security policy.

I edit secure policy on permissions for each service like that for example at s3 storage.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "Statement1",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::<IAM_Number>:user/<IAM_Username>"
            },
            "Action": "s3:*",
            "Resource": "arn:aws:s3:::<S3_Storage_Bucket_Name>"
        }
    ]
}

You can allow upload files for auth users with security policies.

There is example about your situation. https://docs.aws.amazon.com/AmazonS3/latest/userguide/example-bucket-policies.html
