Thanks for the the quick response and helping me rule out the other possible issues. I think I know what’s happening here. As a quick sanity check, would you mind setting another env var in your function and see whether that fixes the object being undefined? In the global scope of your function:

process.env.X_GOOGLE_NEW_FUNCTION_SIGNATURE = true;

Followed by a redeploy. Super appreciate your help in tracking down this issue!
