> Null exception error with DBCP Controller service and AWS parameter provider
> ----------------------------------------------------------------------------
>
> Key: NIFI-10951
> URL: https://issues.apache.org/jira/browse/NIFI-10951
> Project: Apache NiFi
> Issue Type: Bug
> Components: NiFi Stateless
> Affects Versions: 1.18.0, 1.19.0
> Reporter: Lucas Read
> Priority: Major
>
> I have a AWS Secrets Manager parameter provider configured and assigned to a
> process group. I am trying to execute the process group as a stateless flow
> but getting a null exception returned. It works when I do not run it as a
> nonstateless flow but not when it is stateless.
