I’m using llama-index to read from various sources and creating one VectorStoreIndex for each. I’d like to query information from all those sources, and it seems that SubQuestionQueryEngine should allow doing that. But it only gives me errors… need some examples on its use (what I found online, didn’t work).

    tool_git = QueryEngineTool(
        metadata=ToolMetadata(name="git", description="Github",),
        query_engine=query_engine_git,
        )

    tool_jira = QueryEngineTool(
        metadata=ToolMetadata(name="jira", description="Jira",),
        query_engine=query_engine_jira,
    )

    multi_query = SubQuestionQueryEngine.from_defaults(query_engine_tools=[tool_git, tool_jira]


multi_query.query("how many jira tickets opem?")

Traceback (most recent call last):
