Script_score query does not support [query]

**Hey everyone,

i'm trying to apply a custom score using script score but i'm facing this issue...i would really appreciate your help

Here's the query i'm using for that.

my query was based on the documentation of Elastic about script_score which includes a query under script_score. Heer is the link to Elastic documentation Script_score query documentation **
