Hi,

Seems UserTask persistence is enabled, make sure you have following dependency added in pom.xml 

    <dependency>
      <groupId>org.jbpm</groupId>
      <artifactId>jbpm-addons-quarkus-usertask-storage-jpa</artifactId>
    </dependency>

    <dependency>
      <groupId>org.kie</groupId>
      <artifactId>kie-addons-quarkus-persistence-jdbc</artifactId>
    </dependency>
