Incorrect "string | string" type generated from the swagger.json using oneOf statement

[8Duke8]

Here is a part of the schema: The oneOf condition for phone property below incorrectly generates the type "string | string" as shown in result below (even in the latest version 8.0.0).

SOURCE:

"/users/{userId}": {
      "put": {
        "operationId": "putUserAsAdmin",
        "requestBody": {
          "content": {
            "application/json": {
              "schema": {
                "type": "object",
                "properties": {
                  "phone": {
                    "oneOf": [
                      {
                        "type": "string",
                        "pattern": "^(\\([0-9]{3}\\) ?|[0-9]{3}-)?[0-9]{3}-[0-9]{4}$|^\\d{10}$"
                      },
                      {
                        "type": "string",
                        "minLength": 0,
                        "maxLength": 0
                      }
                    ]**
                  },
                  "name": {
                    "type": "string"
                  },
                  "email": {
                    "type": "string",
                    "pattern": "^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,}$"
                  },
                  ...

RESULT:

export type PutUserAsAdminRequestBody = {
  phone?: string | string;
  name: string;
  /**
   * @pattern ^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$
   */
  email: string;
  ...
};
