Manually modify the corresponding file(s) and apply the changes. In this case go to your js/redactor-osticket.js file, open in any text editor, find the line with imageUploadData, change the word imageUploadData to imageData, and save the file. After that you may need to restart the server and/or php-fpm to clear any server-side cache. Since we are dealing with JS you should also clear any browser cache, cookies, and sessions to ensure nothing is cached on the browser side. You should be good to go after that.
Cheers.
