The REST connector reads the response improperly.

The response is missing or has an incorrect Content-Type header.

1. Confirm whether the Content-Type header is missing or blank.
2. Check the Content-Type your application receives is valid for text content.
   Pega Platform reads the following Content-Type header values as text. If the Content-Type header is not a recognized text content type, Pega Platform reads the data as binary content.

   • text/*
   • message/*
   • application/

     atom+xml	jwt	xhtml+xml
     atomcat+xml	rss+xml	xml
     atomdeleted+xml	soap+xml	xml-dtd
     ecmascript	wsdl+xml	xml-external-parsed-entity
     http	wspolicy+xml	xml-patch+xml
     javascript	x-www-form-urlencoded	xmpp+xml
     json	xhtml	xop+xml

3. If you did not receive a content type from the endpoint or if the content type is incorrect, you can decode the Base64 content and revert it to text.
