Thanks for the issue report!

Do you have a code excerpt that reproduces this issue? I tried reproducing it myself without success.

Ah, found a repro. Are you calling deleter.end(null) by chance?

[franck34]

Hi ! thanks for your reactivity !

Below my code

var s3Options = {
    key: 'xxxx',
    secret: 'xxxxxxxx',
    bucket: 'xxxxxx-s3'
};

var knoxClient = knox.createClient(s3Options);

var listerDev = new S3Lister(knoxClient,{prefix:'dev/12345'});
var deleterDev = new S3Deleter(knoxClient);

deleterDev.on('error',function (err) {
    console.log('on error','deleterDev', err);
});

listerDev.on('error',function(err) {
    console.log('on error','listerDev', err);
});

try {
    listerDev.pipe(deleterDev);
} catch(e) {
    console.log('try catch error',e.message);
}

Would you mind adding an .on('data', ...) listener to listerDev? I am curious what is being passed to deleterDev. I believe it's something null at some point.

Alternately, if this is test data and you're comfortable doing so, you could send me the credentials to that bucket and I can reproduce and investigate on my own.

[franck34]

Yep, it's for test. Let me send you an email.

Hi

I tried to debug myself, but no time/enought knowledge.

Switching back to old school extension for knox client.
