The SPRING_APPLICATION_JSON environment variable seen by them CLAMP container is the following one :

SPRING_APPLICATION_JSON={ "spring.datasource.camunda.url": "jdbc:mariadb:sequential://clamp-mariadb.include "common.namespace" .:3306/camundabpm?verifyServerCertificate=false&useSSL=false&requireSSL=false&autoReconnect=true&retriesAllDown=2147483647&failoverLoopRetries=2147483647", "spring.datasource.cldsdb.url": "jdbc:mariadb:sequential://clamp-mariadb.include "common.namespace" .:3306/cldsdb4?verifyServerCertificate=false&useSSL=false&requireSSL=false&autoReconnect=true&retriesAllDown=2147483647&failoverLoopRetries=2147483647" }

The replacement for the namespace isn’t done correctly by helm.
