Helix Control-M Agent upgrade using the provision agent::update API command fails for Agents earlier than 9.0.20.280 and Agents that were upgraded to Agent 9.0.20.280 from an earlier version.
The following exception is printed:
Exception in thread "main" java.lang.NullPointerException
        at com.bmc.controlm.services.provision.AgentUpdater.showComponentsToInstall(AgentUpdater.java:170)
        at com.bmc.controlm.services.provision.AgentUpdater.confirm(AgentUpdater.java:122)

error:   provision saas_agent_update failed

To prevent this issue from occurring, use the ctmcfg utility to update the SAASCONF.dat configuration file prior to the upgrade, as follows:

• Through a command prompt, run the relevant command on each machine where an impacted Agent is installed:
  • On Linux:

    ctmcfg -TABLE SAASCONF -ACTION UPDATE -PARAMETER SAAS_ENV_TYPE -VALUE prod

  • On Windows:

    ctmcfg -AGENT <instance_name> -TABLE SAASCONF -ACTION UPDATE -PARAMETER SAAS_ENV_TYPE -VALUE prod
