Variable handling
I am programming a script in appscript.
executes in an action in an SBM form. the execution ends in the execution of a .bat with parameters.
The first inconvenience is the value of one of these variables (description,of type text), which is a text field with spaces and the .bat receives x number of parameters, I need to send all of these as one, I tried several options but they didn't work for me. the second drawback is handling with dates. (fecha_inicio of type datetime)
and the third is the user who started the workflow(requested_byof type user)

I share my code, any contribution will be very well received. thank you
