Array of objects are displayed as array of string on swagger UI

This is my doc of a service

{
    description: "Returns the Todos of a user",
    tag: "TODOs",
    definitions: {
      create_response: {
        type: "object",
        properties: {
          data: {
            type: "array",
            items: [
              {
                type: "object",
                properties: {
                  id: {
                    type: "string",
                  },
                  taskOwner: {
                    type: "object",

                      email: {
                        type: "string",
                      },
                      image: {
                        type: "string",
                      },
                      userName: {
                        type: "string",

On swagger UI the response body is displayed as

I am not sure why it's happening. Can anyone help

Do you perhaps have multiple usages of create_response also in another services? These names have to be unique in the whole specification.

[RajatKumarChahar]

Yes, it's unique. This is happening to all the API's doc. Whenever there is an array its always shows as ["string"]

[RajatKumarChahar]

Now I've used

return {
          [model]: modelSchema,
          [`${model}_list`]: {
            title: `${modelName} list`,
            type: "array",
            items: { $ref: `#/components/schemas/${model}` },
          },
        };

above code to generate the definitions but still in every [${model}_list] it shows [string]

Could you post the generated swagger specification json? (You can use the docsJsonPath option, if you have not enabled it yet) (You can also test it yourself in https://editor.swagger.io/ what the problem is)
