Express with TypeScript: Global Middlewares Don't Match Types.

[hariacharya80]

So, this is kinda confused question. I found out that the latest version of express and it's types does have a issue, at least with me.

You can understand it if you view the issue below:

and the version is as follows:

but this issue did not existed in the previous version of express and/or it's types:

is this an actual issue or I'm being dumb. Haven't slept for 2 days straight lol 🤣
can anyone replicate and see if it's a genuine issue before opening it?

for more reference the middleware is as follows:

export async function exceptionHandler(error: unknown, req: Request, res: Response, next: NextFunction) {
  try {
    console.log(error);
    if (error instanceof KnownError) {
      return res.status(error.statusCode).json({ message: error.message });
    }
    return res.status(500).json({ message: 'Internal Server Error' })
  } catch (error) {
    console.error('Handling Request Exception Failed')
    return;
  }
}

update to latest express version and types v5+ and your problem should be solved.
mark as solved if fixed
