…ion fails GetOnFly may return (nil, err) when the client factory fails to create a client (e.g. logservice.NewClient times out). truncateFromRemote only handled ErrClientPoolClosed, so on any other error it ran defer client.Putback() on a nil *wrappedClient and panicked (SIGSEGV), crashing the TN. Return on any error from GetOnFly, matching the sibling Get() path. Adds a regression test. issue matrixorigin#24861 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
