Welcome to SO. Please write a title that describes the problem. The first part of your title is totally redundant, as almost everyone who asks a question is seeking for help and the second part seems to describe the broader task but not the specific problem. Please also read [ask] — jps, May 12 '22 at 08:47

I don't know the exact context of what you are trying to do, I will however take a shot in the dark.

The error you are seeing implies that you are asking for something that doesn't exist, based on the way you are trying to import express-jwt.

When code modules in javascript are created they can have named exports and a default export.

From your error it looks like you are importing using the following statement

import expressJWT from 'express-jwt'

This is asking for the 'default' export from that module. Looking at the NPM page for the package it looks like expressJWT is a named export. If this is the case, you would need to modify your import statement to the following

import { expressJWT } from 'express-jwt'

I hope this helps. For next time, try adding your code that is causing the error to help others to answer.

//var { expressjwt: jwt } = require("express-jwt");
import { expressjwt } from "express-jwt";
const requireSignin =expressjwt({
  secret: process.env.JWT_SECRET,
  algorithms: ["HS256"],
});

export default requireSignin;

or

var { expressjwt: jwt } = require("express-jwt");

const requireSignin =jwt({
  secret: process.env.JWT_SECRET,
  algorithms: ["HS256"],
});

export default requireSignin;
