| Description |

It appears like the classic execution engine is being used even though we expect SBE to be enabled. See this Evergreen build. The problem manifests in different ways. For example, plan_cache_sbe.js expects that a cached plan has cachedPlan.queryPlan.slotBasedPlan, but cachedPlan.queryPlan does not exist.
In idhack.js, we are expecting an IXSCAN because SBE is enabled but instead see the classic engine's IDHACK:
