Error when use some javascript expression

[dhanyg]

Hello, i'm trying using edge with express. However i got error when try using javascript typeof and optional chaining inside .edge file.
The code:

@if(typeof errors != 'undefined')
    <div class="alert alert-danger" role="alert">
        {{errors.testFile?.msg}}
    </div>
@endif

The errors:

undefined:20
  if (typeofthis.context.resolve('errors') !== 'undefined') {
  ^

ReferenceError: typeofthis is not defined

}

Previously i used that expression in ejs template and it works.
Any suggestion? Thanks before..

Hi
I've made this adapter to use Edge with Express, but unfortunately I can't help you with Edge issues.
Maybe you can find help here, https://github.com/edge-js/edge

Thanks for the reply, and many thanks for your effort. I really like this template engine. Btw for my issues, I have found alternative solution..
