  Hello Siarhei,

  I have the same problems on multiple instances. Local development doesn't work at all, and all my team's developers can't work on apps. It looks like old zat tools still work, but our workflow heavily depends on zcli tools.

  But, I have only Unknown initialization object: null Expected Object or Function. error in the console, and nothing else.

  Having the same problem also. Difficult to deploy any changes at the moment in case it breaks things.  Was a great feature when it was working!

  Hi everyone, we appreciate your patience as we've been troubleshooting the issue. We identified the source of the bug and have rolled out a fix. You should now be able to resume testing apps using the local development server with ZCLI.

  Please let us know if you are continuing to experience issues.

  Hello Zach Anthony,
  I still have the same problem for some locations in manifest.json. Here, what I have in my app, and it doesn't work:

  
  "location": {
    "support": {
      "nav_bar": {
        "url": "assets/index.html#location=nav_bar",
        "autoHide": true
      },
      "ticket_sidebar": { "autoLoad": false },
      "new_ticket_sidebar": { "autoLoad": false },
      "background": {
        "url": "assets/index.html#location=background"
      }
    }
  }
  
  
  

  I played around, and found two cases when it works:

  "location": {
    "support": {
      "nav_bar": {
        "url": "assets/index.html#location=nav_bar"
      },
      "ticket_sidebar": { 
        "url": "assets/index.html#location=nav_bar" 
      }
    }
  }
  
  

  "location": {
    "support": {
      "nav_bar": {
        "url": "assets/index.html#location=nav_bar",
        "autoHide": true
      },
      "background": {
        "url": "assets/index.html#location=background"
      }
    }
  }

  It looks like apps with location  { "autoLoad": false } break local development.
  
  Best regards,
  Andriy

  Hello Zach Anthony,

  Any news on my last comment? I see this topic has Answered label now, and I don't want it to be missed. But unfortunately, the local development is still not working for almost every app for my team, so we are forced to use zat tools. 
  It breaks our development process, which relies on zcli tools, and adds a lot of frustration to work. 

  Best regards,
  Andriy

  Hey Andriy,
  
  Mind if we move your issue into a ticket as it seems to be a separate bug from the rest of the thread? 
  
  Thanks!

  Hi Team,

  I am still facing the issue.

  I am using windows wsl and zendesk sandbox. My version details are as following:

  root@XXXXXXX/zendesk-shell# zcli --version
  @zendesk/zcli/1.0.0-beta.24 wsl-x64 node-v14.17.3

  Error:

   Access to fetch at 'https://xxxxxxxx.zendesk.com/agent/tickets/' from origin 'http://localhost:4567' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

  Hey Sahib, 
  
  That doesn't look to be related to the local server bug. Are you using secure settings by chance?
