Key to boto3.client.get_batch_prediction() OutputURI

Question

I'm trying to download the Output file from boto3.client.get_batch_prediction(). I figure the key is the filename bit of OutputURI so I'm doing client:

    response = batch.get_batch_prediction()
    if response['Status'] == 'COMPLETED':
        key = response['OutputUri'][response['OutputUri'].find('Output_'):response['OutputUri'].find('.csv')+4]
        s3 = boto3.resource('s3')
        s3.meta.client.download_file(settings.AWS_S3_BUCKET_OUTPUT, key, '/tmp/hello.txt')

But this returns

An error occurred (404) when calling the HeadObject operation: Not Found

I take this to mean the file isn't there. That means I've got my key wrong so how do I find it?

This might also be a permissions problem. Do you have the required permissions to call HeadObject on the key? — spg, Feb 28 '17 at 19:29
@spg that's what I thought and I've asked the administrator who tells me I have the permissions — HenryM, Feb 28 '17 at 19:46
I got the `key` wrong. When I read the documentation carefully I clearly had put in the wrong `key`. Sorry everyone. — HenryM, Mar 02 '17 at 08:29
