title: Dojo - Failed to load resource: the server [...] responded with a status of 404
body: <p>I am using Worklight 6.1.0.1. I created a new workspace and created a new dojo app (no changes to the created Hello Worklight app). When I run the app in the preview mode in Safari, I get 5 errors in the browser console telling me that it failed to load several dojo javascript classes:</p>
  <blockquote>
  <p>[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (favicon.png, line 0)</p>
  <p>[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (deviceTheme.js.map, line 0)</p>
  <p>[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (core-web-layer.js.map, line 0)</p>
  <p>[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (dojo.js.map, line 0)</p>
  <p>[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (mobile-ui-layer.js.map, line 0)</p>

  <p>The Dojo Library Requests view shows requests for layers/core-web-layer.js.map, dojo/dojo.js.map and layers/mobile-ui-layer.js.map. Copying these to the project does not help.</p>
  <p>Why does it ask for -.js.map resources? I haven't seen this notion and google returns no decent results on that.</p>
