Actual Behavior

The URL of all sketches in a collection is always https://editor.p5js.org/<user>/sketches/undefined.

Expected Behavior

It should link to the actual sketches, so the URL should include the sketch ID instead of undefined.

Steps to reproduce

1. Create a new collection
2. Create a new sketch
3. Save the sketch
4. Add the sketch to the newly created collection
5. Open your collection
6. Try to click on the sketch, the URL is wrong

I can’t consistently reproduce this. Sometimes it works and sometimes not. Try creating new collections and add the existing sketch to that. I’m not sure but it might always only happen with the second collection.
