Since I don’t have your full setup in front of me, I’m gonna make an educated guess based on the error and the screenshots you shared.
From what I can see, the issue happens when your main workflow calls the cotizador sub-workflow. It works fine in manual test mode, but during live execution the inputs show up empty — and that’s why you’re getting the Cannot read properties of undefined (reading 'toString') error.
That usually happens when the sub-workflow expects a value (like patente_lead) but doesn’t receive it properly at runtime.
It could be:
The AI Agent is sending the data in a different format than what cotizador expects (maybe as a raw string instead of an object).
The sub-workflow call isn’t mapping the inputs right — maybe it’s expecting direct values but getting something nested.
Or one of the fields is coming in as null or undefined, and your flow tries to do a .toString() on it without checking first.
Here’s what I’d try:
Run the flow in debug mode and look at what’s actually being passed in right before calling the sub-workflow.
Make sure all the inputs that cotizador expects are really present in that payload.
If needed, use a Set or Function node to reshape the data before sending it to the sub-workflow.
If you can share the actual JSON coming from the AI Agent or show how your sub-workflow node is configured, I can help fine-tune it for you.
