After running the script, and looking at the logs, there was a message
"unable to load JNA native support library, native methods will be disabled.
java.lang.UnsatisfiedLinkError: Native library (com/sun/jna/linux-s390x/libjnidispatch.so)"
Though it started, I looked into the problem.
in the lib folder, there is the filel 'jna-5.5.0.jar'.
Inside it, there wasn't a folder com/sun/jna/linux-s390x.
So I went to the page https://github.com/java-native-access/jna/blob/master/lib/native/linux-s390x.jar and downloaded the linux-s390x.jar.
Opening the file, you can find the file you want. Create a folder with name linux-s390x and the libjnidispatch.so file inside the jar.
Replace the old jna-5.5.0.jar for the one you created.
After that, I run the elasticsearch without any warnings.
Hope it helps someone.
