>                 Key: NIFI-4956
>                 URL: https://issues.apache.org/jira/browse/NIFI-4956
>             Project: Apache NiFi
>          Issue Type: Bug
>    Affects Versions: 1.5.0
>            Reporter: Joseph Percivall
>            Priority: Major
>
> To reproduce:
>  * Create a PG with a process in it with a CRON driven scheduling strategy
>  * Start version control of the PG
>  * Attempt create a new PG by "import"ing the versioned flow from above
>  * Notice that an Error occurs that says "Value '* * * * * ?' is not a valid Time Duration and the processor exists but has Timer driven scheduling.
>  * Also, notice that the PG is partially created (if there are other components they may be created) but is not versioned
> This also occurs when upgrading a flow but with a slightly different error message
> "Failed to update flow to new version due to java.lang.IllegalArgumentException: Value '* * * * *?' is not a valid Time Duration"
>  
> I checked the flow_storage of the registry instance and it does have CRON_DRIVEN for the scheduling strategy.
