[jira] [Created] (NIFI-7995) Requesting create Parameter Context
via API with Parameters null generates an NPE
Daniel Chaffelson created NIFI-7995:
---------------------------------------
Summary: Requesting create Parameter Context via API with Parameters null generates an NPE
Key: NIFI-7995
URL: https://issues.apache.org/jira/browse/NIFI-7995
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.12.1, 1.10.0
Reporter: Daniel Chaffelson
org.apache.nifi.web.api.ParameterContextResource.validateParameterNames(ParameterContextResource.java:403)
gets very upset if you submit a JSON with null for the Parameter listing instead of an empty or populated list. It is a minor thing, but probably worth tidying up in the validator.
Discovered because NiPyAPI defaults to Python 'None' for unpopulated properties.
Full logged error is:
2020-11-09 13:20:28,612 ERROR [NiFi Web Server-22] o.a.nifi.web.api.config.ThrowableMapper An unexpected error has occurred: java.lang.NullPointerException. Returning Internal Server Error response.
java.lang.NullPointerException: null
