Debugging update painless script is hard as errors are returned in a
not really readable JSON format.
To gain debuggig time, wrap search.origin_update calls when running
elasticsearch tests in order to catch painless script errors and
pretty print them.
Tests will also immediatly fail when such errors are detected.
Below are the kind of pytest reports we can obtain (I intentionnally
added errors in the script code):
