Problem Description

When using the _id field in an aggregate function, ES throws the following exception:

java.lang.NullPointerException: Cannot invoke "String.length()" because "v" is null

Simple example query resulting in an exception:

FROM metrics-*.otel-* METADATA _id
  | STATS c = COUNT(_id) BY service.name

This behavior appears to be indeterministic because it sometimes succeeds, but most of the time not.

The same happens also with other aggregate functions (e.g. ... SAMPLE(_id,10) ...).

Changing the above query by simply exchanging _id with * resolves the issue:

FROM metrics-*.otel-* METADATA _id
  | STATS c = COUNT(*) BY service.name

Steps to Reproduce

  1. Go to https://otel.demo.elastic.co/
  2. Go to Try ES|QL in Discover
  3. Select a time range of 1 hour
  4. Run the following query:
FROM metrics-*.otel-* METADATA _id
| STATS c = COUNT(_id) BY service.name
