Error running expo build:ios

Please provide the following:

  1. SDK Version: 38.0.0
  2. Platforms(Android/iOS/web/all): Android/iOS

Hi all,

I am running into an error when I attempt to build the IPA file for my expo project from my Windows command line. After I enter my Apple ID and password, I get an error stating “Authentication with Developer Portal Failed!”.

Is anyone familiar with this issue? I can’t tell if it is a problem with how I’m running Expo or with how I’ve configured my Apple account. I have an Apple Developer account but have not purchased an enrollment in their developer program, nor am I aware of what the “Apple Developer Portal” is. Do I need to upgrade my Apple Developer account , or is the issue with Expo?

Thanks for any help you can provide.
