[NBestsuNgan]

In few day ago, I able to use vertexAISearch with ADK Agent but now i can't and it look like the code not recieve None but default is None more than that VertexAISearchDataStoreSpec is also not have in types.

did anyone have any idea about this?

I also rollback version from 1.4.2 -> 1.3.0 -> 1.2.1 -> 1.2.0
from 1.3.0 -> 1.2.1 -> 1.2.0 the code can use vertex ai search tool BUT it doesn't not return any doc that associated with data store which connect to vertexAISearch App but if we search in console it work but in ADK Agent it doesn't
