Unexpected token in JSON during JSON.parse()

Question

I am getting an error "Unexpected token in JSON at position 26" for a webRTC offer. I am using an ajax call to take the offer from a db and return it as plain text to parse into a JSON object. When I try to parse the string, I am given an "Unexpected token in JSON" error.

Here is the JSON as a plain string

 {"type":"offer","sdp":"v=0

 "}

and the code

$.ajax({
    url: "./php/actions.php",
    type: "post",
    dataType: "text",
    data: {type:'retrieve', roomid:roomid},
    success: function(data){
        //data is plain text from string of offer retrieved from db
        $('.termp').text(data); //used to check raw text data for now
        var offerSDP = JSON.parse(data); //returning error when trying to convert to json
        remoteConn.setRemoteDescription(new RTCSessionDescription(offerSDP)); //needs an object
    }
});

I have had success using a copy and paste method before in a different application where I get raw text data and paste it into a text area and then JSON.parse(text-area.val()) and successfully set sessionDescription, but the methods are seemingly the same but yield different results.

In JSON, plain new line character is forbidden. You need to replace it with \n.
