---------------------------------
Summary: NPE when updating parameter context without
"inheritedParameterContexts" array
Key: NIFI-9416
URL: https://issues.apache.org/jira/browse/NIFI-9416
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.15.0
Reporter: Joe Gresock
Client code that submit parameter context updates will likely fail due to the
following exception when the "inheritedParameterContexts" array is omitted from
the request entity:
{code:java}
java.lang.NullPointerException: null

Since clients prior to 1.15.0 did not know about inherited parameter contexts,
the only workaround is to add "inheritedParameterContexts": []
