Configured content-type is [application/json] but actual content-type is [text/html]

Summary:

Content (please ensure you mask any confidential information):

I have a REST end point which return below response on POSTMAN:

{
"type": "text/csv",
"data": "QnVzaW5lc3NVbml0TmFtZTtSZWNlaXB0TWV0aG9kTmFtZTtSZWNlaXB0TnVtYmVyO2NydF90eXBlO3JlY2VpcHRkYXRlO2dsZGF0ZTtBbW91bnQ7Q3VzdG9tZXJOYW1lO0N1c3RvbWVyQWNjb3VudE51bWJlcjtDdXJyZW5jeUNvZGU7Q2x1YiBOdW1iZXI7RXhlcnAgSW52b2ljZSBJRDtQYXltZW50IFNvdXJjZQozMDAwMDAwMTExNDcxMjI7OzEwMj…………………."
}

The data is appearing in Base64 format. (I shortned the text.)

When configred in OIC with Response as JSON type I am getting below error:
