[jira] [Updated] (NIFI-10853) UpdateAttribute - expression language syntax error not caught until processor runtime
[ https://issues.apache.org/jira/browse/NIFI-10853?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Nissim Shiman updated NIFI-10853:
---------------------------------
Description:
The UpdateAttribute will not show any alerts when the following expression language value is used for a property value:
{code:java}
${filename:equals('testFile'}
{code}
This is also true when using the 'Verify Properties' button. (A green arrow is returned saying "Component Validation Passed").
The processor will start, but when a flowfile passed through on runtime, though, it will fail
with error
{code}
org.apache.nifi.attribute.expression.language.exception.AttributeExpressionLanguageException: Invalid Expression: ${filename:equals('testFile'} due to Unexpected token '}' at line 1, column 28. Query: ${filename:equals(testFile}
{code}
(This is not the case with RouteOnAttribute, which will leave the processor in an invalid state, flagging this as an alert, until the expression is corrected.)
