I tried doing this on the lightning cloud and faced the same issue. This seems to be an error due to an older code version deployed on the lightning cloud.

I tried doing it locally instead and it works by cloning this repo at its latest state and then running it.
You could try cloning the repo on your machine, and running the command

git clone https://github.com/Lightning-AI/LAI-research-template-App.git
cd LAI-research-template-App
lightning run app app.py --cloud

# this will ask for the lightning cloud credentials which could be obtained from the steps displayed while running the above command.

@zippeurfou, we want to update the app gallery with the latest sha to avoid this error on clone and run.

Closing this since the SHA is updated, and both Launch and clone & run buttons are working correctly.
