How to add custom Error Handler?

[ak99372]

I'd like to add a global error handler either on express or resourcejs level (to do additional logging/handling) but I don't see an options or params to do that and on top the default error handler seems to swallow the errors.

const error = (err, req, res, next) => {
      if (err) {
        res.status(400).json({
          status: 400,
          message: err.message || err,
        });
      }
      else {
        return next();
      }
    };

    routeStack = [...routeStack, error.bind(this)]

Any suggestions on how to let errors through to express middleware or have a custom error handler added to resourcejs?
