  - name: handlerTimeoutInSec
    value: <REPLACE-WITH-HANDLER-TIMEOUT-IN-SEC> # Optional. Default: "60". Timeout for invoking app handler.
  - name: disableEntityManagement
    value: <REPLACE-WITH-DISABLE-ENTITY-MANAGEMENT> # Optional. Default: false. When set to true, topics and subscriptions do not get created automatically.
