py command breaks in ps1 but not in PowerShell terminal

The py -3 -m venv venv command works when typed manually into a Powershell terminal, but breaks when called from a ps1 script.

What specifically must be changed in the code below in order for the setup.ps1 script to successfully run the py -3 -m venv venv command when the setup.ps1 is called from outside using the Invoke-Command -FilePath setup.ps1 or a similar replacement command?

The contents of the setup.ps1 command are:

py -3 -m venv venv

The command that calls setup.ps1 including the error together look like:

PS C:\path\to\dir\containing_setup_py> Invoke-Command -FilePath setup.ps1
Invoke-Command : Parameter set cannot be resolved using the specified named parameters.
