Javascript error: Cannot read properties of undefined (reading 'newRowInputsArray')

[Obeewan]

I am following a lab tutorial and according to instructions there should be a input and output column when you click "Add examples". I also clicked the "Add input column" and it also throwing a javascript error. Yes I am using a incognito version of chrome. Version 137.0.7151.55

I’ve seen similar issues with this error in labs before. A few things to check:

1. Make sure you followed all previous steps exactly, sometimes a missing step or an overlooked setting causes this.

2. Try clearing your browser cache completely (even in incognito, some things might persist), or switch to a different browser like Firefox to see if it’s Chrome-specific.

3. Double-check if the tutorial was updated recently or if there’s a known bug with that lab version.

If it’s still failing, you might want to manually refresh or reset the lab environment (if possible) to start fresh. I’ve found that reloading the page and restarting the lab can fix temporary glitches like this.

Hope that helps!

I'm having the same issue even trying from a personal project, the example feature seems bugged.

Just checked this today and looks like they have fixed it.
