Streamlit App does not deploy

My python streamlit app works correctly when I run the code myself. However when I deploy it, it continuously gives the following error on the promote stage. I’ve tried doing all kinds of deployments (Static, Autoscale and Reserved).

exec [sh -c python3] error=exec: already started
2024-02-14T12:00:14Z error: The deployment failed to initialize due to a configuration or code error. Check the logs tab for more information. For additional support, please post on and a staff member will take a look.

My app is a chatbot that references openai for responses.

Hi @rameezpak1000 , welcome to the forums!
Just to confirm, does your repl has a webserver?
If so, try deploying it as Autoscale, and send the full Logs of the deployment.

Hi, here are the logs from an autoscale deployment

Hi @rameezpak1000 !
In your .replit file, try changing the run variable under [deployment] to:

run = ["python3", ""]

Hope this helps!

Hey, it still gave the same error.

For reference, my only has the following code in it:

import os

os.system("streamlit run")

whereas the file has all the code for the streamlit application, in case that helps in any debugging.

In that case, wouldn’t that be your deployment command?

it could be but running python3 should also execute the same thing no?

Not sure, perhaps it’s causing an error when called indirectly like that?

that shoulnd’t be the issue, however I do notice one thing… when I click on Run to test my application streamlit prompts me for an email address, which obviously requires a manual answer in the shell. Could it be that no response here is causing the issue? Since when I enter my email or leave it blank and press enter, my application runs fine. but in deployment we dont have the option to

You’ll have to do some kind of workaround then, you can’t type into deployment shells.

I had the same error and fixed it using this -
