Clients are properly patched, however, at the end, the error message occurs. When clients are patched using SSM without Action Chain, no such error message occurs. No such error occurs when other supported operating systems are patched using SSM and Action chain.

1. Update the salt-minion first on the affected clients using SSM
2. Patch the "overall" system using SSM and action chain
