EDIT: This was a mendix issue and has been fixed in 9.18.3 and 9.20 “We fixed an issue where uploading an image with an unsupported EXIF orientation tag failed. (Ticket 170543)” Hi all, We have some users reporting that they get a java error when uploading an image: 10:22:37APPERRORConnector: Uploading file failed: scala.MatchError: 0 (of class java.lang.Integer) [User 'username' with session id '74766c72-XXXX-XXXX-XXXX-XXXXXXXXbe34' and roles 'Manager'] 10:22:37APPERRORConnector: com.mendix.systemwideinterfaces.MendixRuntimeException: scala.MatchError: 0 (of class java.lang.Integer) 10:22:37APPINFOat com.mendix.util.classloading.Runner$.withContextClassLoader(Runner.scala:23) 10:22:37APPINFOCaused by: scala.MatchError: 0 (of class java.lang.Integer) I’ve found its due to the type of file they are using, the image is in .jfif format which is a variation of .jpeg just with some compression. Does anyone know if it’s possible to allow Mendix to read this format?
