Azure AI ML: Prompt Flow deployment to Online endpoint results an error Execution failure in 'vector_db_lookup': (ImportError) cannot import name 'Vector' from 'azure.search.documents.models' (/azureml-envs/prompt-flow/runtime/lib/python3.9/site-packages/

Question

Hello

In Azure AI Machine Learning studio I'm working on designing model via Prompt Flow, using Vector DB Lookup tool to get data from documents stored in Vectorized DB . Flow is working as intended in a prompt Flow environment.

However when i deploy model to online endpoint i get exception:

Execution failure in 'vector_db_lookup': (ImportError) cannot import name 'Vector' from 'azure.search.documents.models' (/azureml-envs/prompt-flow/runtime/lib/python3.9/site-packages/azure/search/documents/models/init.py)

Previously i used this exact flow in same endpoint and it was functional in both Prompt Flow and Managed Online Endpoint. Then i cloned flow and have updated it, not changing vector_db_lookup; deployed Prompt Flow in Online Endpoint and get problem listed above.

I tryed to roll back, get back to proven working flow and deployed it to endpoint but now it also leads to listed problem (everything is fine in Prompt Flow environment, but problem in endpoint.

Same issue happens when I create new prompt flow from scratch, using example template and then deploying to new endpoint.

Vector database wasn't changed for months, search explorer works fine with this vector DB index.

Any hints what can cause it?

Thanks!

Andrey
