-To prevent possible infinite looping, Segment checks your Function code to ensure that you don't have `https://fn.segmentapis.com` included. That URL is used to send data to a Source Function. Including that URL in your Function code is a sign that an infinite loop may occur so Segment ensures you can't save your Function if that URL is included. To fix this, please remove that URL from your Function code.
