NullPointerException when bool query used in script score

[davidb-e4s]

Hosted ES in elastic cloud (GCP) v7.5.1

I am trying to use script_score to modify a score. I use a bool query but when running this under script_score it results in a null pointer exception. If I remove the bool query and run a simple match query it works.

Steps to reproduce:

Please include a minimal but complete recreation of the problem, including
(e.g.) index creation, mappings, settings, query etc. The easier you make for
us to reproduce it, the more likely that somebody will take the time to look at it.

1. Attempt to use script_score with a bool query

Example query below
{ "query": { "script_score": { "query": { "bool": { "filter": [ { "range": { "validFrom": { "from": null, "to": "2020-01-08" } } } ] } }, "script": { "source": "_score + (doc['boostScore'].value)", "lang": "painless" } } } }

This example works

{ "query": { "script_score": { "query": { "match": { "message": "elasticsearch" } }, "script": { "source": "_score + (doc['boostScore'].value)", "lang": "painless" } } } }

Thanks for reporting @davidb-e4s , this bug is already fixed by #48425 so I hope you don't mind if I close this. The next minor release (7.6.0) will contain the fix.

OK thanks @jimczi do you have an ETA on the release?

As a matter of policy, we don't give ETAs, even approximate, sorry. However you can apply the workaround described here in the meantime.
