NullPointerException[Cannot read field "dynamic" because "this.config" is null

Hi Guys,

Elasticsearch Version: 7.10.2
Open Distro Security Version: 1.13.1.0

I’m trying to enable internal users in opendistro and getting the following error when I do execute following command,

bash /usr/share/elasticsearch/plugins//opendistro_security/tools/securityadmin.sh -nhnv -nrhn  -icl -cacert /etc/elasticsearch/certs/MyRootCA.pem -cert /etc/elasticsearch/certs/admin.pem -key /etc/elasticsearch/certs/admin.key -t internalusers -f  /usr/share/elasticsearch/plugins/opendistro_security/securityconfig/internal_users.yml

Error :

Can anyone guide me to resolve this issue ?

Thanks.
