Hey @kapitanoppa,
Your input is probably nested into output or something like that:

"output":{
    "email": "[email protected]",
    "booktime": "01/01/2026"
}

In your sub-workflow trigger you can enable ‘Accept all data’

This will allow you to test, see what data is coming and adjust your mappings.

Ah… I see you are using agent tools…
Maybe it has something to do with the tool support of the model.
I personally don’t use tools too much because they are too unpredictable yet.
