Prevent Upload of PDF files

Innovator inn = this.getInnovator();
// Get the File Type of the file being attached
Item file = this.getRelatedItem();
string filetype = file.getProperty("file_type");
// 7869D76D50ED4BD4985BECB20B1102F7 - Corresponds to the PDF File Type
// 1F6BEC4E228E4FEDA65D1C3647BDA96D - Corresponds to the 3D PDF File Type
if (filetype == "7869D76D50ED4BD4985BECB20B1102F7" || filetype == "1F6BEC4E228E4FEDA65D1C3647BDA96D") {
// Returning an error here will prevent the file from being added
return inn.newError("Cannot upload PDF File");
}
// Returning this will let the Document File be created
return this;
