Neural Search Leads to "modelId is marked non-null but is null" when Targeting Multiple Indices #758

Closed imbarazz closed 4 months ago

imbarazz commented 4 months ago

Note: this error was observed on OpenSearch 2.11 running on AWS cloud.

Performing a neural search against an alias, or performing a multi-search with multiple indices in a single header leads to the following error: "_null_pointerexception: modelId is marked non-null but is null". This is problematic when searching across different indices, each with their own embedding model.
