I have Nifi and Nifi Registry deployed via Docker. I'm trying to integrate ScriptEventHookProvider. https://nifi.apache.org/docs/nifi-registry-docs/html/administration-guide.html#scripteventhookprovider

Here is my providers.xml:

Referenced script file notify.sh exists and is placed inside of the registry container:

I tried relative and absolute paths, but nothing helps me - I get the error:

java.io.IOException: Cannot run program "/opt/nifi-registry/nifi-registry-current/registry_hooks/notify.sh": error=2, No such file or directory

enter image description here

So my question is, how to set script path and working directory correctly? Why do we need both of them?

Problem was in .sh file: it requires LF endings. I had CRLF. So I converted line endings using VS code, and now everything works fine.
