             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.
