ReferenceError is not defined

I check exists object in template, if exists then work good. But if no exists I get exception ReferenceError: e is not defined. Do I know somehow?

<input type="text" id="username" name="username" placeholder="Username" class="text ${(e) ? 'error' : ''}" autocomplete="off">

@jmsherry well spotted! Just applied the fix, so pull in the latest 😃

Wow, yeah I got this too. And here it is; a days old issue with the same. Cool 😃

In my case, the template uses a variable that is not in locals.

The actual problem is: It’s not catchable so the server dies.

I tried:

res.render('template', { locals }, err => {
    next(createError(500, `Template error: ${err.toString()}`))
})

And

try {
   res.render('template', { locals })
} catch (err) {
    next(createError(500, `Template error: ${err.toString()}`))
}

In both instances, the web server dies. I need to fix my variables. I know. But I also want to protect my server against a rogue commit to my template variables and nicely show a 500 page instead of ending up with a dead web server.
