@ylasri Can you give more details to reproduce? The code that could trip this is dead (not referenced by anything in production). It's trivial to remove, but I want to understand how you were able to cause that code to run.

@rjernst I'm running a cluster using this docker image

FROM docker.elastic.co/elasticsearch/elasticsearch:8.17.0
RUN /usr/share/elasticsearch/bin/elasticsearch-plugin install --batch mapper-murmur3
RUN /usr/share/elasticsearch/bin/elasticsearch-plugin install --batch mapper-size

[rjernst]

Can you elaborate on what actions you took on the cluster? Perhaps a series of (minimal) steps like (1) create this index, (2) index this doc, (3) run this query?
