Hello! I have started using LlamaIndex and i created a small rag pipeline using two QueryEngineTools for two different datasets and its working great. The app chooses correctly which tool to use its time and responds correctly, but i want to add a web search tool, like TavilyToolSpec, for information it cant retrieve from the two datasets. Trying to add this tool to the agent, always yields errors with the metadata or query. How can i combine these two different types of tools?
