title: Is there a way to debug Firestore?
body: <p>I use Angular and Firestore for my application. Unfortunately every CRUD tutorial I find doesn't cover the necessary rules to keep the application safe. I would only find rules for the previous solution by Google (not Firestore).</p>
  
  <p>Now I did make the following rules for a create request:
  Check if user ID matches the stored user ID. 
  Check if the request size equals 5. 
  Check if the request contains 5 fields with specific names. 
  Check if the fields have the proper type (string, timestamp etc). </p>
  
  <p>Somewhere, it breaks. I haven't touched it in a while but I really don't know where it starts to say "nope, won't let you in". There are no errors. </p>
  
  <p>My question is, is there a way to debug what you exactly send and see what function doesn't let you in? If not, is there anyone that can provide example code of their CRUD rules? I would highly appreciate it</p>
