Issue Summary: My tool call executes successfully, and I get the expected result string in the tool_call_result. However, in the conversation node that follows, the variable ({{result}}, {{tool_call_result}}, etc.) does not render or speak. What I've Tried: Confirmed the webhook returns a valid JSON result Tried returning the result as a plain string, and as an object ({ "AvailableTimes": "..." }) Verified toolCallId matches across Vapi and Make.com Tried all variable formats: {{result}}, {{tool_call_result}}, {{result.AvailableTimes}} Logs confirm tool call and result are present, but message output is always silent Suspected Bug: The new June 2025 Vapi workflow update may not expose tool result variables correctly in message nodes.
