fetching from twitter api (node.js) [closed]

I am trying to reach followers count by username by this apiapi.twitter.com/labs/2/users/by/username/:username

https://github.com/All1nol/omarBentoGrid/tree/master/backendwhat i have done

app.js

Official links: https://developer.twitter.com/en/docs/twitter-api/users/lookup/api-reference/get-users-by-username-username#tab0https://www.postman.com/twitter/workspace/twitter-s-public-workspace/request/7360366-92c5e7ea-40ab-478c-a4bc-71910df3e06a

Even when i try to run curl or request from postman it doesn't return anything. I am 99% sure that it is not about the code i wrote.
