title: The specified key does not exist - While copying S3 object from one bucket to another
body: <p>I am trying to copy a S3 object from one bucket to another and the response is looks like this - </p>
  
  <pre><code>`object(stdClass)#24 (3) { 
            ["error"]=&gt; array(2) { 
                ["code"]=&gt; string(9)
                 "NoSuchKey" ["message"]=&gt; string(33)
                  "The specified key does not exist." 
         }
            ["code"]=&gt; int(404) ["headers"]=&gt; array(1) {
        ["type"]=&gt; string(15) "application/xml"
      } 
   }
  </code></pre>
  
  <p>`</p>
  
  <p>Here is how the code looks - </p>
  
  <pre><code>var_dump($this-&gt;s3-&gt;copyObject('bucket_1','bucket_1/'. images/1.jpg, 'bucket_2', 'bucket_2/images')).die();
  </code></pre>
  
  <p>According to method signature of <strong>copyObject</strong> I would need to supply <strong>Source object URI</strong> and <strong>Destination object URI</strong>.</p>
  
  <p>Anyone please help me to know what's going wrong here ?</p>
  
  <p>Thanks.</p>
