Handling Spaces in fields of incoming POST request in Action argument

Question

I have a requirement where I am getting a post request payload from a system to my CAP application where fields contains blank spaces. Now I wanted to create Identifiers for my actions arguments to take the incoming input. I wanted to know how we can put spaces while creating our Identifiers.

Entity Definition:

Incoming payload :

{ "data": [ { "Security ID": "6788361819397", "Work Order ID": "GE5AWO00000054", "Worker ID": "BE5AWK00000035", "First Name": "Luís", "Last Name": "Barreto", "Worker Email": "[email protected]", "Start Date": "11/22/2023" } ]}

When I am trying to pass the values without spaces I am getting this Deserialization Error :

Thank you

I read some documentations but did not got any positive results
