Truncates SSH Keys

[aleexharris]

Have tried to use v3 of this action to load the private key of an SSH key that I am using as a GitHub deploy key. The key is being truncated to 167 characters, no matter if I export the key using environment variables or as a step output. I have verified that the key works by using it directly as a GitHub action secret.

Example failure:

- name: Log in to 1Password
  id: load_ssh_key
  uses: 1password/load-secrets-action@v3
  with:
    export-env: false
  env:
    SSH_KEY: op://cicd_github/github/private key

- name: Setup SSH agent with deploy key
  env:
    SSH_AUTH_SOCK: /tmp/ssh_agent.sock
  run: |
    ssh-agent -a $SSH_AUTH_SOCK > /dev/null
    ssh-add - <<< "${{ steps.load_ssh_key.outputs.SSH_KEY }}"
    mkdir -p ~/.ssh
    ssh-keyscan github.com >> ~/.ssh/known_hosts
    echo "SSH_AUTH_SOCK=$SSH_AUTH_SOCK" >> $GITHUB_ENV
