  <p>After investigating on the web, I found that it may help to change the "Permission level" on the "Database" tab of my "Database project properties" from "safe" to either "Unsafe" or "External". <img src="https://i.stack.imgur.com/DC1dk.png" alt="Dtabase Project Properties"></p>
  
  <p>But the error is still coming up after doing mentioned change!</p>
  
  <p>Does anyone possibly have any idea why this is happening?</p>
  
  <p>Any help appreciated in advance.</p>
