Azure search indexer and skillset | how to get rid of warning when indexing deleted blobs

Question

In the Azure portal, I created a RAG environment with a search instance, a skillset and an indexer by using the Import and Vectorize data option.

Adding document works like a charm.

When I delete (soft delete option enabled) a document from a container and start the indexer, the blobs are deleted from the container and the related documents (result of a splitting and embedding skillset) are removed from the search service

The indexer console shows warnings like these:

operation

Projection.IndexProjections.SearchIndex.<indexname>

Message 

Could not generate projection from input '/document/pages/*'. Check the 'source' or 'sourceContext' property of your projection in your skillset. =$(/document/pages/*) ?map { "chunk": $(/document/pages/*), "doc_name": $(/document/metadata_storage_name), "source": $(/document/owner), "title": $(/document/title), "vector": $(/document/pages/*/vector) }

The skillset in play

It is just warnings and I think I do understand why they are shown but it would be great if there id a way to suppress them or work around them.

Any idea or insight is much appreciated
