title: How to fix chrome-extension inline JavaScript invocation error?
body: <p>I'm making a chrome extension however I seem to get the following error when I try to fire up an onclick() event. </p>
  
  <pre><code>Refused to load the script 'https://apis.google.com/js/client.js?onload=handleClientLoad' because it violates the following Content Security Policy directive: "script-src 'self' blob: filesystem: chrome-extension-resource:"
  </code></pre>
  
  <p>and </p>
  
  <pre><code>Refused to execute inline event handler because it violates the following Content Security Policy directive: "script-src 'self' blob: filesystem: chrome-extension-resource:". Either the 'unsafe-inline' keyword, a hash ('sha256-...'), or a nonce ('nonce-...') is required to enable inline execution.
  </code></pre>
  
  <p>This is my manifest.json :</p>

   },

     "scripts":["background.js"]
  },

    {
     "matches": ["http://*/*", "https://*/*"],
