fix(generate): prevent type error when existing task (#3793)

this commit updates the generate task to suppress instances
of hitting ctrl-c during the generate task would cause an error
to be printed to the console:

> TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument
> must be of type string. Received undefined

this was reported to have happened in v5.8 of zsh on MacOS,
and was replicated using PowerShell on Windows.
