Firebase数据库规则的语法错误

Question

{ 
"rules": { 
    "Users": { 
     "$user_id": { 
      // grants write access to the owner of this user account 
      // whose uid must exactly match the key ($user_id) 
      ".write": "$user_id === auth.uid" 
     } 
    } 
    "$businessName": { 
     ".write": "root.child('Users').child(auth.uid).child($businessName).child('Permission s').val() === 'MODERATOR'" 
    } 
} 
} 

这给了我一个错误：保存规则错误 - 第10行：期望'，'或'}'。该错误说，由于某种原因，我错过了一个括号，我错过了一个逗号或什么？

Answer 1

由于@Frank面包车Puffelen说我只是缺少你错过了'，前 “$ BUSINESSNAME”
