Hi

How are you building the app? Does the above error cause the build to fail?

keytool is distributed with Java, so as a workaround you should be able to install Java and make sure that keytool is in your PATH.

Problem is solved . I updated JFK to the latest vision that’s (jdk16) and it was able to generate the keystone.
