Code Review

This pull request adds the error code 101 to the STOP_ON_ERROR_CODES array in node_manager.rs, updates the corresponding unit tests to verify this change, and updates a warning log message in phase_node.rs to refer to 'Node data or config' instead of 'Database for node'. There are no review comments, and I have no feedback to provide.
