Agent Crash When there are no documents for embedding.

[zvigrinberg]

Agent crashes at the beginning when no documents at all available for embedding.

Container images with utilities and tools are possible and exists, and they contain no application code at all.

If it's expected to have files for embedding anyway ( at least 1 file) , then if one wants to invoke the analysis on such container images, then one must pass in different documents ( like scripts, manifests, configuration files, text files, documentation, directories structure, etc.), but in case there are 0 documents in the input , the agent should just log that error message and move on to listen for next requests , instead of crashing unexpectedly.
