No issue with your assistant – we might need to upgrade our native assistant node to look into this edge case and fetch all tools. In the meantime to unblock you I created a custom node (its a feature on Gumloop, you can create on yourself).
You can use the custom node I created normally within any workflow or create a custom node yourself. Once we’re able to upgrade the native node I can send an update here.
