If you provide your Apple account credentials we will be able to generate all necessary build credentials and fully validate them.
This is optional, but without Apple account access you will need to provide all the missing values manually and we can only run minimal validation on them.

Reproducible demo or steps to reproduce from a blank project

Must not be logged in to apple account with EAS
Run eas build -> platform iOS -> attempt to login with apple account

Getting the same error on eas-cli/24.3.0 as well

[camchis]

Looks like the endpoint that EAS is using to get the authServiceKey is retuning 404: https://appstoreconnect.apple.com/olympus/v1/app/config?hostname=itunesconnect.apple.com

Fix

Manually grabbing the key from the scripts on https://appstoreconnect.apple.com/login and supplying it to EAS with the EXPO_APP_STORE_AUTH_SERVICE_KEY prefix works for me

export EXPO_APP_STORE_AUTH_SERVICE_KEY='e0b80c3bf78523bfe80974d320935bfa30add02e1bff88ec2166c6bd5a706c42' eas build

I’m encountering the same issue while setting up the first iOS development build for an Expo SDK 57 project.

Environment:

Windows 11 / PowerShell
EAS CLI invoked with npx eas-cli@latest
Active individual Apple Developer Program membership
Apple Team ID is present
Two-factor authentication is enabled
Apple Developer Account and App Store Connect are accessible
This is the project’s first iOS certificate and provisioning-profile setup

Error:

Authentication with Apple Developer Portal failed!
iTunes service key is empty
Error: build command failed.

The failure occurs immediately after entering the Apple ID and password, before the two-factor authentication prompt or credential creation.

[poolnunez]

The same thing is happening to me. Any solutions or ideas?

[omorest]

Same here!

[idobata-r2r]

I’m experiencing the same issue.

Environment:

• Windows 11
• Node.js 24.21.0
• EAS CLI 24.3.0
• Expo SDK 57

When running:
eas build --profile development --platform ios

Apple Developer authentication fails with:

Authentication with Apple Developer Portal failed!
iTunes service key is empty

The error occurs when logging in with my Apple Developer account.

I am also running into the same error when i run the command "eas build --platform ios --profile production"

[proshno]

I'm facing the same issue...tried everything...nothing is working :(

[mlnxsg]

the same!

[lisbejuin]

Same here but I have subverted the problem with a manual setup on the App Store Connect, is very tedious but it's work now...

[proshno]

I could make it work also after dirty patch-works:

Basically, for me, exporting the following environment variables made build go through:

$ export EXPO_ASC_ISSUER_ID="69xxxxxxe-8fxxc-xxx3-exxx-xxxxxxx1"
$ export EXPO_ASC_KEY_ID="7xxxxx7xxxxx"
$ export EXPO_ASC_API_KEY_PATH="Downloaded_AuthKey.p8"
$ export EXPO_APPLE_TEAM_ID="Team ID"
$ export EXPO_APPLE_TEAM_TYPE="INDIVIDUAL"
$ npx eas-cli build --platform ios

However, even then npx eas-cli submit got stuck. To solve I has add the following to eas.json file:

{
  "submit": {
    "production": {},
    "preview": {
      "ios": {"ascAppId": "XXXXXXXX"}
    }
  }
}

As suggested in https://docs.expo.dev/submit/eas-json/#ios-specific-options.

[tstesfamariam]

I was able to build using your method but I am getting the same error when I try to submit using the command, and I have updated the eas.json file and added acsAppId input. eas submit --platform ios --latest --profile production What command have you used to submit..it still asks me for apple ID username and Password and when I enter I get the error. Authentication with Apple Developer Portal failed!

Same issue here on eas-cli 24.3.0.

ASC API-key auth works for certificates/provisioning, but APNs setup still forces Apple username/password auth and then fails with:

iTunes service key is empty

I also created a valid APNs .p8 manually and tried uploading it via eas credentials --platform ios, but EAS still forces user re-auth and hits the same error.

Improvement suggestion: if the user provides a valid APNs .p8, allow it to be stored/used without requiring Apple cookie-based login, and replace the raw assertion with a clearer fallback/error message.
