I want to copy file.

This works perfectly fine, and spits out a list of all files in my space:

s3.listObjects({Bucket: "lospec"}, function(err, data) {});

This code on the other hand:

s3.copyObject({
    Bucket: "lospec",
    Key: newAvatarPath,
    CopySource: oldAvatarPath,
}, function(err, data) {});

Returns this error, claiming the bucket name is wrong:

What am I doing wrong? How is my bucket name wrong?
