Fix vault credentials causing subprocess spawn failure - #246

When aap_username, aap_password, or aap_hostname are defined as Ansible Vault encrypted values (AnsibleVaultEncryptedUnicode), the manager subprocess spawn fails with: TypeError: expected str, bytes or os.PathLike object, not AnsibleVaultEncryptedUnicode This occurs in process_manager.py when building the command array for subprocess.Popen. Vault-encrypted values are subclasses of str but subprocess.Popen requires actual str objects, not subclasses. The issue is particularly visible when using token authentication while vaulted credentials exist in playbook variables, as the credentials are still passed to the manager subprocess as config/fallback values. Fix: Convert all gateway_config credential fields to str() before passing to subprocess.Popen: - base_url: str(gateway_config.base_url) - username: str(...) if ... else "" - password: str(...) if ... else "" - oauth_token: str(...) if ... else "" The str() conversion works because AnsibleVaultEncryptedUnicode inherits from str and __str__() returns the decrypted value. The conditional check ensures None values become empty strings rather than "None". Reproducer: Use vaulted aap_username/aap_password in group_vars and run any module. The bug triggers during manager subprocess spawn. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Add comprehensive test coverage for the vault credentials subprocess fix: - Unit test: tests/unit/.../test_vault_credentials.py Tests that AnsibleVaultEncryptedUnicode credentials are converted to str() before being passed to subprocess.Popen. Mocks vault credentials and verifies the conversion happens correctly. - Integration test: tests/integration/targets/vault_credentials_test/ Tests vault-like credentials work in real scenarios: - Organization check with string-converted credentials - Token creation with credentials - Token authentication while credentials exist in variables This regression test ensures the specific scenario that triggered the bug (token auth + vaulted creds in vars) continues to work. - Changelog: changelogs/fragments/fix_vault_credentials_subprocess.yml Documents the bugfix for users. The unit test is comprehensive and tests the exact code path that was buggy. The integration test validates end-to-end functionality. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Create vault_credentials_mock molecule scenario to test the vault credentials subprocess fix: - Tests organization and token creation with vault-like credentials - Tests token authentication while credentials exist in variables (the specific scenario that triggered the bug) - Tests both connection modes: local and http persistent - Verifies idempotency The test uses Jinja2 string filter to simulate vault credentials, as actual AnsibleVaultEncryptedUnicode objects are only created when values come from vault-encrypted files.
