Cloud Error : Oh no. Error running app - but no errors in log

Hello,

I’ve successfully deployed an app locally but when I run it in the cloud it crashes without explanation. I only get “:exclamation: Streamlit server consistently failed status checks” in the logs.

link to my app : https://datascientest-projet-bda-london-firefighters.streamlit.app/
my github repo to the project: https://github.com/Julline27/BDA_Firefighters/tree/main

Any help is appreciated.
