Trying to deploy a PR on open

Question

As the title says, trying to deploy on PR open. However, greeted with the:

Deploying PR #94 to preview environment...
🔗 Linking to existing project: ***

Unauthorized. Please login with `railway login`

When I do try to authenticate, I get the non-interactive constraint

This is my workflow:

- name: Deploy to PR Preview Environment
        run: |
          echo "🚀 Deploying PR #${{ github.event.number }} to preview environment..."

# Link to your existing project
          echo "🔗 Linking to existing project: ${{ secrets.RAILWAY_PROJECT_ID }}"
          railway link --project ${{ secrets.RAILWAY_PROJECT_ID }}

# Add database service if this is a new environment
          echo "🗄️ Ensuring database service exists..."
          railway add postgresql 2>/dev/null || echo "PostgreSQL service may already exist"

# Deploy the application
          echo "🚀 Starting deployment..."
          railway deploy --detach

echo "⏳ Waiting for deployment to complete..."
          sleep 60

echo "🔍 Checking deployment status..."
          railway status

echo "🌐 Getting application URL..."
          DEPLOY_URL=$(railway domain 2>/dev/null || echo "Domain will be auto-assigned")

echo "✅ PR deployment complete!"
          echo "🔗 Application URL: $DEPLOY_URL"
          echo "🌟 Environment: $ENVIRONMENT_NAME"
        env:
          RAILWAY_API_TOKEN: ${{ secrets.RAILWAY_TOKEN }}
