I am trying to get a file from the amazon bucket but it says “string  
contains null byte”. any idea how to get the file to download like a  
regular file? The file is there at the location.

f = Heypub.value @bucket  
send\_file( f , :type =\> “FileExtns[ext][‘mime’]”, :disposition =\>  
‘attachment’)

f.

or this version is the same thing:

f = S3Object.value @bucket, ‘mybucket’

Verify it the file is ok first by writing to the filesystem.

You may need to attempt to isolate the problem without much information.

also are you using [http://amazon.rubyforge.org/](http://amazon.rubyforge.org/) ?

the examples that it presents look similar to yours.

It gives you the same error?

I mean open a file and write it to the server. open(‘filename.png’,‘w’)  
do |  
etc.

If the above and send files gives you the same error s very likely that  
you  
are using the api mistaken and need to check your assumptions and  
understanding carefully.
