Error Code 4000, User has no permissions for specified resource

I have deployed the server part of my app and I have copy/paste the link in my browser and launch it, but I Get the following error:
{“code”:4000,“message”:“User has no permissions for specified resource”,“errorData”:{}}
The Application ID, and key are right and also the permission for my table: person

This error is related to users permissions, have you set any? You can check it for each role on Users -> Security Roles tab in console.

thanks Sergey
I have solved the issue.
I did have a mistake with the API Key.
