UDA: Add support for returning NULL in Execute Automation running mode

1

Hi,

I tried various approaches to return an actual NULL value via Execute Automation, this wasn't possible. Instead these are default values:
Text: ""
Decimal: 0
Boolean: false
DateTime: 0001-01-01T00:00:00

If I would ask an AI, whether I could use WEBCON for a specific use case, and it uses the Exceute Automation endpoint, it will get "false" even if the use case hasn't been defined.

Best regards,
Daniel
