@Vapi So, I have built the simplest use case for the integrated Google Sheets "too" in workflows, and it does not work. The same exact "tool" works fine in an assistant. The workflow is just "hello, what is your name," then extracts {First_name} and {Last_Name} in that conversation node - send that to the tool node for appending first and last name to a Google sheet. Then a second conversation node for salutation. The workflow never gets past the tool. The logs don not show a tool being invoked. I have tried a lot of different ideas, but nothing seems to work. What am I missing?
