Intercepter-ng android not creating necessary files

Am running android 7.1 with root and busybox. As soon as I launch the app it immediately crashes. When I check a logcat I get;

java.lang.RuntimeException: Unable to start activity ComponentInfo{su.sniff.cepter/su.sniff.cepter.ChooseActivity}: java.lang.RuntimeException: java.io.IOException: Cannot run program "su" (in directory "/data/data/su.sniff.cepter/files"): error=2, No such file or directory

Root permissions are granted. It appears that interceper-ng isn't creating its files in the data/data/su.sniff.cepter. could somebody make a flashable zip in order to fix the issue?
