------------------------------------

             Summary: UpdateAttribute - expression language syntax error not caught until processor runtime
                 Key: NIFI-10853
                 URL: https://issues.apache.org/jira/browse/NIFI-10853
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Nissim Shiman


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}
