----------------------------------
Summary: NPE in ParameterProviderSecretsManager when
SecretReference has null fullyQualifiedName
Key: NIFI-15842
URL: https://issues.apache.org/jira/browse/NIFI-15842
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 2.9.0
Reporter: Kevin Doran
Assignee: Kevin Doran
When a connector's configuration contains a SECRET_REFERENCE property with
providerName populated but fullyQualifiedSecretName set to null (representing a
secret-type property that has not been configured yet), the NiFi framework
throws a NullPointerException during connector installation:
{code}
Error fetching parameters for ParameterProvider[id=...]: Cannot invoke
"String.startsWith(String)" because "fqn" is null
{code}
*Root cause:*
{\{ParameterProviderSecretsManager}} collects \{{fullyQualifiedName}} from all
\{{SecretReference}} objects into a list and passes it to
\{{ParameterProvider.fetchParameters()}}. When a reference has a null FQN
(valid state — the secret property is defined but not yet configured), the null
is added to the list. The default \{{fetchParameters(context, list)}}
implementation in \{{ParameterProvider}} iterates the list and calls
\{{startsWith()}} on each entry, which throws NPE on the null.
