Cannot create temp directory: /.jmix/temp

Hello, I created an ubuntu ec2 instance and added tomcat 9. Deployed the war by placing in the webapps directory. When I checkin a file, I get the following error. Caused by: io.jmix.core.FileStorageException: I/O error: Cannot create temp directory: /.jmix/temp I manually created .jmix directory, still same exception. This works in my local windows machine. Please suggest. Also if I specify jmix.localfs.storage-dir = /home/ubuntu/files. Will it work? Regards, Prashanth
