ExecuteScript error - ECMAScript is missing

[#1]

Hi,

moved Ni-Fi 1.16.3 folder from one destination to another and now getting error for ExecuteScript processor:

'Script Engine' validated against 'ECMAScript' is invalid because Given value not found in allowed set 'Clojure, Groovy, Lua, Python, ruby'.

Any idea what's wrong?

Thanks a lot. Ludvik

ok, I found this https://en.wikipedia.org/wiki/Nashorn_(JavaScript_engine)

With the release of Java 11, Nashorn was deprecated citing challenges to maintenance, and has been removed from JDK 15 onwards.

@Luwi , please note that NiFi currently only supports Java 8 and 11.

Cheers

Andre
