Recently, I created a project for my learning. When I ran it using the command “ng-serve -o”, it successfully ran on the browser at “
https://localhost:4200 ". However, it gave me a console error, which is as follows:
    
      Uncaught (
      
      in promise) 
      
      TypeError: 
      
      Cannot convert 
      
      undefined or 
      
      null to 
      
      object
      
    at 
      
      Function.
      
      keys (<anonymous>)
      
      
    at companion-bubble.
      
      js:
      
      1465:
      
      19726
      
    at 
      
      Generator.
      
      next (<anonymous>)
      
      
    at 
      
      Ln (companion-bubble.
      
      js:
      
      1465:
      
      19144)
      
      
    
  
  Upon analyzing the error, I discovered that it was caused by the Loom extension that I had downloaded for video recording on my laptop. Once I removed this extension from my browser, the error disappeared.
