title: BOBJ. RESTFull WebService API. Get list of Data Providers returns "404" message
body: <p>I use RESTFull WebService API (BOBJ 4.1) to retrieve the information about the reports in the repository. </p>
  
  <p>When I try to derive the list of data providers, it works file for most of the reports. However, for some of the reports I get back the "(404) not found" message. I appreciate that it's a valid response for reports which don't have any data providers, but I'm sure that the reports I get the 404 message for definitely have one or more data providers. I also don't expect it to be related to the permissions, because I don't get the "access denied" message and I can open the "problematic" reports using the Rich Client.</p>
  
  <p>I use the following link:</p>
  
  <pre><code>http://{servername}:{port}/biprws/raylight/v1/documents/{reportID}/dataproviders
  </code></pre>
  
  <p>Has anyone experienced this kind of a problem before? Am I missing something? </p>
