Deploying with Manifest.json

Hi - I am trying to deploy a shiny app using a manifest.json file. When I use the one click deploy it is not seeming to recognize it. The app.R, manifest.json and requirements.txt are all in the same directory. Is there anything I need to do to get it to force recognize the file? I am deploying from Rstudio IDE on a Mac to posit connect using the one click deploy button

My goal here is to get a python environment setup but because it can't detect the manifest.json I am getting

Warning: The reticulate package is installed but no Python environment is available.

however, directly in my code I have: Sys.setenv(RETICULATE_PYTHON = "/opt/Python/miniconda/bin/python")
so I am a bit confused why it wouldn't be working
