Isaac Examples > Awesome Example is no longer displayed

Omniverse Isaac Sim

Hi!！
I was going through the isaac sim tutorial and rewrote some Python files. This may be the reason why some of the “Isaac Examples” menu items, including “Awesome Example”, are not showing up anymore.
How can I solve this problem?Here is the error code.

If you have typo or error in you code. It will not be displayed.

Hi @yoshietoshi104

As @jwson3 indicate, the extension is not enabled due to the following error:

Edit the file (at line 14) and make sure the indentation is correct

It looks like the error was caused by incorrect indentation of the python program. Thanks everyone for your answers.
