Moving google apps script to v8 file upload stopped working from sidebar
问题 I have a script running that works as intended. But moving the script to v8 makes the script not working. And I can't find a solution. I've cleaned up the script and tested it in the old engine and still works, but in v8 still doesn't working. It's a sidebar in a spreadsheet where to upload a single file to my google drive. Here the basic in the Html file <body> <h1>File Uploader</h1> <form> <input type="file" name="myFile" id="file"> <br> <input class="blue" type="button" id="submitBtn"
