ION API Node response content type

Hi,

I declared a new API in ION API. When I test it inside ION API documentation I can select the response content type(the api provider uses different kinds of xml formats).

However when I use the API inside my ION workflow the response content type dropdown under Output Parameters tab is disabled. Below is the first bit of my documentation which has the response content type.

swagger: '2.0'
info:
version: '1.5.0'

Did you figure this out? I'm having the same problem.

I suspect, this could be due to vendor-specific MIME types that start with the prefix vnd. on your GET method. I don't think we support vendor specific types.

Can you try and add a regular 'application/xml' as an additional type to your swagger, re-upload the documentation in gateway and see if it solves your problem?

The service I'm using is one that I built with C# .NET 5.0.

Here's what I did.

In the C# Startup.cs class. I added this line to build a Swagger 2.0 instead of an OpenAPI 3.0. I don't think IONAPI likes OpenAPI 3.0.
1. app.UseSwagger(c => c.SerializeAsV2 = true);
Using Vignesh's suggestion. I added this line to each method in the Swagger file.
1. "produces": ["text/plain", "application/json", "text/json"],
