Swagger interface - "TypeError: Failed to fetch" with a valid response

Question

Swagger interface - "TypeError: Failed to fetch" with a valid response

I just removed the latest version of Swagger from the Git repository (3.0.19) using: https://github.com/swagger-api/swagger-ui.git and updated my API to use the new version.

git describe --tags for confirmation and my version now: v3.0.19-6-gaab1403

I am having the problem described here in which my answer is 403 (I see this in the inspector in the browser), and although I have the answer to 403 error, I still get the message TypeError: Failed to fetch.

Here is a snippet of my definition regarding answer 403:

                    "403": {
                    "description": "Forbidden",
                    "headers": {
                        "Access-Control-Allow-Origin": {
                            "type": "string"
                        }
                    }
                },

: - API, Asp.net Core

API Swagger. API, Asp.net Core, Apache Swagger Apache. CORS (Cross Orgin Request).

I have to modify my API code to allow a CORS request using the following code: - Declare in the Startup.cs file that has the class "StartupShutdownHandler"

private readonly string MyAllowSpecificOrigins = "_myAllowSpecificOrigins";

Added code section in ConfigureServices method.

var str = ConfigurationHandler.GetSection<string>(StringConstants.AppSettingsKeys.CORSWhitelistedURL);
        if (!string.IsNullOrEmpty(str))
        {
            services.AddCors(options =>
            {
                options.AddPolicy(MyAllowSpecificOrigins,
                builder =>
                {
                    builder.WithOrigins(str);
            });
            });
        }
