I am trying to add existing apps script projects to a standard Cloud Platform Project so that I have more control over the errors and logging. I have no trouble migrating recently created apps script projects to my new Cloud Platform Project, but I can't get older apps script projects to do it.
New apps script projects have it right in the resources menu:
But the older apps script projects completely lack the "Cloud Platform project..." option under resources:
I can't seem to find any documentation on why this is the case, or on how to add older scripts. Can anyone help me here?
Thanks!
