I know this isn’t a CF forum but I wanted to share what I ran into yesterday. I was doing an cf script http call to do a put on a text file to a 3rd party API and found that update 3 causes the files to be empty. I downgraded and the problem went away. Maybe I save those that aren’t using Railio some time.
