ReferenceError: Portal is not defined

CarolineGlazer2 — Sun, 12 Dec 2021 01:31:03 GMT

Hi everyone,

I'm trying to set up a web app using Esri Leaflet, but using ArcGIS API for JavaScript to handle authentication. I've managed to get authentication working (I think), but I'm getting an error when I try to define a new portal to check the user is logged in "ReferenceError: Portal is not defined." I'm pretty new to javascript and I assume I'm using the require / function syntax incorrectly somehow - I copied bits and pieces from here: Access services with OAuth 2.0 | ArcGIS for Developers

Any insight would be very much appreciated - thank you! Code below:

You closed off the require function at line 53, which means the displayMap function fell outside of it. You have to move that closure to line 70
