------------------------------------
Summary: NiFi Toolkit pg-import no longer works without specifying
input-source
Key: NIFI-14223
URL: https://issues.apache.org/jira/browse/NIFI-14223
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 2.2.0
Reporter: Chris Sampson
NIFI-14134 (https://github.com/apache/nifi/pull/9611) introduced the abilty to
{{pg-import}} a Flow Definition from a JSON file directly into NiFi.
Unfortauntely, the same change means it is no longer possible to import a Flow
Definition from NiFi Registry when an {{input-source}} is not specified in the
NiFi Toolkit command, because a {{NullPointerException}} is thrown when trying
to create a {{File}} resource from the null/empty String {{inputSource}}:
