Initialization Keycloak data

Hello,
Can any one describe for me the process of initialization data in Keycloak via scripts in cluster MOSIP, because by executing keycloak-init it doesn’t work.

Thanks

To ensure proper execution, please verify that the Keycloak service is active and operational prior to running the ./keycloak-init.sh script. Additionally, if any errors were encountered during the execution of the script, could you kindly provide us with details regarding the observed error?
