 »   Error: Netlify CLI has terminated unexpectedly
This is a problem with the Netlify CLI, not with your application.
If you recently updated the CLI, consider reverting to an older version by running:

npm install -g netlify-cli@VERSION

You can use any version from https://ntl.fyi/cli-versions.

Please report this problem at https://ntl.fyi/cli-error including the error details below.

I don’t understand why it shows bad auth when my mongodb username and password are correctly stored in a .env file in the netlify/functions directory of my project. (I can assure you they are correct and stored with the proper variable name)

Also below is the fetch function mentioned in the error message:

const mongoose = require('mongoose');
const Profile = require('./model');

exports.handler = async function (event, context) {
  const username = process.env.MONGODB_USERNAME;
  const password = process.env.MONGODB_PASSWORD;
  mongoose.connect(`mongodb+srv://${username}:${password}@cluster0.********.mongodb.net/`);
  const { httpMethod } = event;

  if (httpMethod !== 'GET') {
    return {
      statusCode: 405,
      body: 'Method Not Allowed',
    };
  }

  try {
    const employees = await Profile.find();

    return {
      statusCode: 200,
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify(employees),
    };
  } catch (error) {
    console.error('Error retrieving all employee data:', error);

    return {
      statusCode: 500,
      body: `⚠️⚠️⚠️ ALERT!! ERROR IN RETRIEVING ALL EMPLOYEE DATA: ${error}`,
    };
  }
};

Try running your project in WSL. Then you can see the complete error message which is not visible in Windows.
