- multiple (boolean) (required) - shows if this field may have multiple values (uses when you have the list with details of some items in your document, e.g. a list of products).
- required (boolean) (optional) - shows if the field is required for extraction, so human won't be able to submit Human Task without specifying the values for all required fields.
- helperText (string) (optional) - an additional text which is shown if the value is invalid due to additional validators specified by regexp settings.
- regex (string) (optional) - specify regexp function to use for values validation.
- regexFnc (list of string) (optional) - list of names of validator functions, which are specified by in "regexFunctions".
