StackFrame constructor doesn't accept object with null prototype:
> const StackFrame = require('stackframe');
undefined
> new StackFrame({fileName:'lol'})
{ fileName: 'lol' }
> new StackFrame(Object.assign(Object.create(null),{fileName:'lol'}))
{}
> new StackFrame('lol'.match(/(?<fileName>\w+)/).groups)
{}
$ npm ls stackframe
