I have the same issue.

Same here. Digging deeper with my almost nonexistent Lambda skills, I noticed this code fragment in the Lambda@Edge function which seems to handle that request:

     status: '302',
      statusDescription: 'Found',
      headers: {
        location: [{
          key: 'Location',
          value: `/?${body}`,
        }],
      },
    };

So as I read it, it takes the request body (which is multipart form encoded) and attaches it as-is to the redirect Location: header. This data contains multiple CRLF (\r\n).
