title: Console Log behaviour - Cannot read Object property
body: <p>I'm building an angular web app.</p>
  
  <p>In the ngOnInit of the component:</p>
  
  <pre><code> public ngOnInit() {
      this.log.debug("INSTANCE", this.Instance);
      this.log.debug("ACTIVITY",this.Instance.entity);
      this.log.debug("CREATED AT", this.Instance.created_at);
          // Other staff...
   }
  </code></pre>
  
  <p>I get the following result:
  <a href="https://i.stack.imgur.com/JG041.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/JG041.png" alt="enter image description here"></a></p>
  
  <p>How can be possible so? I cannot read a property of the object that should be populated as the first log shows.</p>
  
  <p>If I print the keys as suggested</p>
  
  <pre><code>Object.keys(this.Instance).forEach(data =&gt; {this.log.debug(data)});
  </code></pre>
  
  <p>I don't have the aspected key.</p>
