 * - string: Direct string value or expression evaluating to string
 * - number: Direct number value or expression evaluating to number
 * - boolean: Direct boolean value or expression evaluating to boolean
 * - array: Expression that evaluates to an array, e.g. ={{ [1, 2, 3] }} or ={{ $json.items }}
 * - object: Expression that evaluates to a plain object (not an array — use the array type for arrays), e.g. ={{ { key: 'value' } }} or ={{ $json.data }}
 * - binary: Property name of binary data in the input item, or expression to access binary data from previous nodes, e.g. ={{ $('Node').item.binary.data }}
