> ------------------------------------
>
> Key: NIFI-3595
> URL: https://issues.apache.org/jira/browse/NIFI-3595
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.1.1
> Environment: API version is 0.6.1 and deployed on 1.1.1
> Reporter: Mahfuzul Amin
> Priority: Major
>
> GetFTP processor throws NullPointerException randomly on 1.1.1. Recently we
> have installed the version 1.1.1. We have another server where nifi version
> 0.6.1 is running. According to our observation GetFTP works fine on version
> 0.6.1. To replicate the flows we have copied the flow.xml.gz file from nifi
> 0.6.1 to 1.1.1.Our custom processors are using the API version 0.6.1 in the
> project. The stacktarce is given below:
