Angular 13 SSR serve is failing with error - TypeError: Right-hand side of 'instanceof' is not an object about serve-static

Hi, I have no idea, as even there is no Object.t.createWindow in this module, either.

Well, across the entire code base of express I'm sure instanceof is being used many places. You'd need to narrow down exactly which module your instanceof error is coming from to be able to figure out what is going on at the least. Nothing in express does createWindow, however, as that sounds like a web browser api and express is a server side framework.

Hello, and I'm sorry you are having trouble. Unfortunately, I don't think this module can help, as there is no instanceof in our code base. You can view our code base right here on Github: https://github.com/expressjs/serve-static/blob/master/index.js

Without even an instanceof in our code base, it would seem to be an impossibility to correct an error in the usage of instanceof that doesn't exist. If you can provide further details, perhaps link to where exactly in the code the instanceof error is coming from and/or provide full reproduction steps that shows where this instanceof is in this module, I can re-open the issue. I'm closing now because you may have opened against the wrong module by accident.

@dougwilson , error seems to be invoked at
at Object.t.createWindow as per the stacktrace and yes you are correct on instance of being referenced in line from Parser-Lib module.
So was wondering if these are linked as i couldn't see Parserlib in Server-static dependency tree as well,
Any lead would be really helpful 🙂

Any idea if express is using above methods top in this module as these are part of minified code as part of server bundles generated
