Hey there, I’m trying to deploy a simple app from a repo on streamlit cloud and I get the following error when I click “Deploy!” Any thoughts on how to go about fixing it? There’s no guidance on debugging this. Request failed with status code 400 [image]

Hey @nukebro , Thanks for sharing this question! Are “main” and “app.py” correct? What happens if you try deploying by supplying your repo’s URL instead =?

Yes! It’s the main branch and the entrypoint/streamlit script is app.py. It’s a private repo, but I took a screenshot. It does call on a .env file for the API it uses, not sure if that matters. [image]

And I get the same error trying to deploy via the github url. Does the specific error code mean anything? [image]

Super interesting – do you mind DM’ing me your GitHub username? Also, have you deployed any other private apps on your account?

Will send a DM now - this is my first time trying to deploy on streamlit cloud, so I’m sure have some setting in git wrong :upside_down_face:

@Caroline just kidding, I don’t know to DM on here

If you click on my profile there should be a “Message” button in the top right corner

It looks like I’m limited as a new user and can’t send messages?

Hello, I am facing the save error, did you find a way to solve the issue by any chance?

Hi, I’m experiencing this as well when trying to deploy. I am also unable to send you a DM, the option does not appear.
