Returns SlotFiller Object

- object: The IEntityMeta defines meta information every entity within the system has. These are dates when a resource was created and modified as well as information about the user who initially created a resource and who modified it the last time.
  - `name` string: The display name of the Slot Filler.
  - `type` 'age' | 'date' | 'duration' | 'email' | 'intent' | 'slot' | 'money' | 'number' | 'percentage' | 'regex' | 'temperature': The type of the Slot Filler.
  - `usePositiveOnly` boolean: If set to `true`, extracts only Slots from predefined Keyphrases.
  - `storeResultInContext` boolean: If set to `true`, stores the result in the Context object.
  - `contextKey` string: The key used to store the result in the Context object.
  - `storeInContactProfile` boolean: If set to `true`, the result is stored in the Contact Profile.
  - `profileKey` string: The key used to store the result in the Contact Profile.
  - `storeDetailedResults` boolean: If set to `true`, stores metadata about the extracted Slot.
  - `skipIfResultInContext` boolean: If set to `true`, the user input isn't checked for the Slot that is already in the Context object.
  - `additionalValidation` string: The additional validation expression or script.
  - `resultLocation` string: Determines where to extract the Slot value from. By default, the Slot value is extracted from the user input. You can set a CognigyScript expression in this parameter to override the detected Slot value with a value from the [Input, Context, or Profile objects](/ai/agents/develop/ai-agent-memory/overview). This parameter works only if the user input is recognized and the CognigyScript expression doesn't resolve to a falsy value.
  - `regex` string: The regex pattern to extract specific data from the user input. Used only when the Slot Filler type is `regex`.
  - `slot` string: Specifies which Slot this Filler is associated with, for example, `date` or `airport_code`. Used only when the Slot Filler type is `slot`.
  - `referenceId` string, uuid
  - `_id` string
  - `createdAt` integer: Unix-timestamp
  - `lastChanged` integer: Unix-timestamp
  - `createdBy` string
  - `lastChangedBy` string
