If you want to define the type of items in the array, you can use the items keyword directly with the $ref property. Example: yamlCopy code name: users type: array items: $ref: '#/definitions/User' This assumes that you have a "definitions" section where the "User" type is defined. Adjust the $ref accordingly based on your Swagger definition structure.
