Configure Trigger REST adapter to accept text/html response body

Content

Hello,

I am trying to configure a trigger rest adapter to call an external API that returns a XML text as the response but with the content-type text/html.

How should I configure it since the adapter doesn't allow me to choose the one I want?

If I try to use application/xml for example, I get a 500 response code.

Attached is the error response from OIC and also a success response using Postman to directly call that external API.
