problems with deploying a py-shiny app to shinyapps.io

[cainesap]

Hello,
I'm having some issues in deploying a Shiny for Python app (which works ok locally) to shinyapps.io, which I'll list here:

• I think it may relate to installation of dependencies. I hadn't created a requirements.txt file, as this wasn't specified in the documentation (request 1 is to improve the documentation for deployment to shinyapps.io for py-shiny apps)
• Even though deployemment failed, I think that it created an application in my account, because when I tried to deploy the app again the new error was that I had hit my limit of apps for my account (this new app did not show in the shinyapps.io applications list, but I could terminate it with rsconnect::terminateApp() in R).
• I did manage to deploy an app after fixing the above, but then the app failed because I had a "pip install" command in my app, and this command was not permitted
• I have a git clone then a pip install command in my app, because I'm installing from a repository (not a package available in pypi)
• So I wonder how to do this: shall I have virtualenv in requirements.txt, then activate it from the app, and run the git clone, pip install commands
• However, I can't test the question above because I'm currently getting a deployment error as follows:

Deploying bundle ... 	[ERROR]: shinyapps.io reported an error (calling /v1/applications/13222535): Not Found
Error: shinyapps.io reported an error (calling /v1/applications/13222535): Not Found

Please could someone help? I can't see any running/sleeping apps on shinyapps.io which I can terminate.
thanks in advance!

Update: can ignore most of the above as i've found workarounds / solutions.
Except for the request for improved documentation please @ https://docs.posit.co/shinyapps.io/guide/getting_started/#working-with-shiny-for-python to include instructions on requirements.txt (starting with the fact that such a file is recommended)
Thanks for the great resource!
