I have 403 server error messages when I updated the repo

Hi I have been using Huggingface space for several months now. Today I have updated my streamlit app and pushed a new change. Then the app stopped working and returns 403 error. I am not sure what is happening, and ti does not seem there is a known solution here. Here is what it looks like in actual screen. I tried different browsers with both private window or with log-in. I would appreciate if any information about how I might be able to fix the issue.


Note that I uploaded the model to hugging face separately, and I download the model using the requirements.txt. This has been working since I started using it, but I uploaded another model to hugging face today and changed the requirements.txt and model name in the python file. It works fine locally, but it does not on the cloud.

Thank you so much for any recommendation/help in advance!

I finally figured it out that it was because my old app did not have streamlit version in the yml section, which was necessary to set the space up correctly. I did not notice this change when I push my updates.
