Codemagic APP_STORE_CONNECT_PRIVATE_KEY Provided value is not valid

Question

I'm trying to sign the iOS build on Codemagic using YAML workflow. Following this document I encrypted and added the following environment variables:

1. APP_STORE_CONNECT_KEY_IDENTIFIER
2. APP_STORE_CONNECT_ISSUER_ID
3. APP_STORE_CONNECT_PRIVATE_KEY
4. CERTIFICATE_PRIVATE_KEY

On running the workflow I'm getting error Provided value "VALUE of APP_STORE_CONNECT_PRIVATE_KEY" is not valid. What to make this env variable value valid? I also tried adding base64 encoding for this value, but it still shows the same error.

Here's my codemagic.yaml file:

workflows:
  ios-workflow:
    name: iOS Workflow
    # instance_type: mac_mini
    max_build_duration: 120
    environment:
      groups:
        - store
      vars:
        XCODE_WORKSPACE: "Runner.xcworkspace"
        XCODE_SCHEME: "Runner"                
        BUNDLE_ID: "*MY_BUNDLE_ID*"
      flutter: stable
      xcode: latest
      cocoapods: default
    scripts:
      - name: Set up keychain to be used for codesigning using Codemagic CLI 'keychain' command
        script: |
                    keychain initialize
      - name: Fetch signing files
        script: |
# Failing command with invalid APP_STORE_CONNECT_PRIVATE_KEY
                    **app-store-connect fetch-signing-files $BUNDLE_ID --type IOS_APP_STORE --create**
      - name: Use system default keychain
        script: |
                    keychain add-certificates

make sure you downloaded the private API key from App Store Connect in .p8 format and copied the entire contents when paste into environment variable value field.

Crosspatch

Yes, I'm pasting the entire file along with -----BEGIN PRIVATE KEY-----....-----END PRIVATE KEY-----. Still facing the same error. – Rozek

Correction: I just put the entire key and it worked. Thanks for your input. – Rozek
