error: Error -3 while decompressing: incorrect header check

I was trying to read a compressed file from s3 on ec2 and it did not print any line

for myKey,content in smart_open.s3_iter_bucket(email_bucket):
    with smart_open.smart_open(myKey) as data:
        for line in data:
            print line

Then I ran:

file = smart_open.smart_open(myKey)
for line in data:
    print line

and got the error:

I think this is caused by zlib. Any insight on how to troubleshoot this?

I think I solved the issue by modifying the s3_iter_bucket function and using list(smart_open.S3OpenRead(key)).
