Error deploying a Shiny Express app - shiny/express/app not found

When deploying a shiny express app to Posit Connect, I get the error below. I checked around and it appears that the entrypoint is correct in the manifest and shiny is listed in the requirements. Since it is Connect, I don't really have access to a terminal to do much checking. Anyone see this before?

Error:
Error while loading Python API: Could not import module 'shiny.express.app'. Connect expected to find a file in the application directory named 'shiny/express/app.py'. Please check the entrypoint specified in the manifest.json file or on the rsconnect-python command line. Reason: No module named 'shiny.express.app'.
