在部署到firebase时获得400，规则语法错误

Question

当我运行`firebase部署'时，我会收到以下错误：

Error: HTTP Error: 400, Rules Syntax Error: undefined

这是我的规则。

这是从以下螺栓文件生成的：

    write() {
        return id == auth.uid
    }
}

    validate() {this.fullName.test(/^w.*w/)}
}

        return this.test(/^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i)
    }
}

    write() {
        return this.owner !== null && this.owner == auth.uid
    }
    read() {
        return (this.owner != null && this.owner == auth.id) || this.sessions != null
    }
}

Answer 1

将生成的代码粘贴到火箱控制台中，并尝试上传它，给了我一个更明显的错误：

Error saving rules - Line 141: Cannot have multiple default rules ('$id' and '$sid')

在生成的输出中，我在 sessions": $ id and $ sid"下有2个通配符位置，因为在我的螺栓路径中，我在2个路径中使用了2个不同的变量名称。
