------------------------------------
Summary: String around an expression language in python processor
is cut
Key: NIFI-16001
URL: https://issues.apache.org/jira/browse/NIFI-16001
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 2.9.0
Environment: Podman 5.8.2 with official Nifi image
Reporter: Fabian Reiber
I try to use an expression language in a python processor. It works pretty
fine, but when I use something like "${my_attribute}_foo_bar" (where
"my_attribute" has the value "hello") as the property value, everything after
the expression is cut. Just "hello" is shown. If I use a parameter from the
context like "#\{my_attribute}_foo_bar", it works and the value is
"hello_foo_bar". I was wondering, if I am doing something wrong. But I found
the
[WritePropertyToFlowFile|https://github.com/apache/nifi/blob/rel/nifi-2.9.0/nifi-extension-bundles/nifi-py4j-extension-bundle/nifi-python-test-extensions/src/main/resources/extensions/WritePropertyToFlowFile.py]
processor and tried it. It shows the same behaviour.
It can be workarounded with "${my_attribute:append('_foo_bar')}".
