Invalid regular expression

[bruiserpink]

I want to append a template in my code, but when I use {{dashcase name} in '[]',throw a error: " Invalid regular expression: /xxx/: Range out of order in character class".
Here is the action:

{
    type: "append",
    path: addRouterPath,
    pattern: /(\/\/ -- APPEND PAGE ROUTER HERE --)/gi,
    template: 
    "const {{camelCase name}}Router = [{
        path: '/{{dashCase name}}',
        name: '{{pascalCase name}}',
     }]",
},

My plopjs version is 3.1.1
