S3 upload files with public

Question

I have a website working with nodeJs. In here users can upload their pictures. I'm using Wasabi to store that pictures. My problem is everytime a user send a picture to server it will save it with private condition. Because of that after uploading users can't see the picture. I need to make it public on the bucket so users can see it. My all buckets are free to read but everytime I upload a file it will be private. How can I make every uploaded picture public?

these are my upload params

const paramsForUpload = {
      Bucket: bucketName,
      Key: filePath,
      Body: file.data,
    };
    const options = {
      partSize: 10 * 1024 * 1024, // 10 MB
      queueSize: 10,
    };
s3.upload(paramsForUpload,options, (err) =>{
....
})

My policy

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "AllowPublicRead",
      "Effect": "Allow",
      "Principal": {
        "AWS": "*"
      },
      "Action": "s3:GetObject",
      "Resource": "arn:aws:s3:::bucketname"
    },
    {
      "Sid": "AddPerm",
      "Effect": "Allow",
      "Principal": {
        "AWS": "*"
      },
      "Action": "s3:GetObject",
      "Resource": "arn:aws:s3:::bucketname"
    }
  ]
}

Thanks for helping

You can make public upload with adding

      ACL: 'public-read',

to your upload params like

    const paramsForUpload = {
      Bucket: bucketName,
      Key: filePath,
      Body: file.data,
      ACL: 'public-read',
    };

The bucket policy should refer to the contents of the bucket, with a trailing /*:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "AllowPublicRead",
      "Effect": "Allow",
      "Principal": "*",
      "Action": "s3:GetObject",
      "Resource": "arn:aws:s3:::bucketname/*"
    }
  ]
}
