Just in case, I missed the param for TEXT(" %s ") and get this error. So, I found not quick solution and want to place it here.

Be sure, that you are set the string parameters if you declare wildcard inside of TEXT(“”)
=>
UE_LOG(LogTemp, Warning, TEXT("Objects fetched: %s."),*FString::FromInt(response.Num()));

The solution you provided, using the FString::FromInt() function to convert the response.Num() value to a string, is a good way to provide the necessary parameter for the function.

Thank you for highlighting this!
