My pipeline has a dynamic target that generates a bunch of files, but possibly none.

In the case when one of the branches generates no files, the pipeline stops with the following error:

Error : _store_ a target must have at least one output file.

The documentation says it is the intended behaviour indeed for external output files:

the return value is a character value of paths to existing files and nonempty directories.

A pain point in that case is it does not seem to be an error in the target but a failing assertion of the targets package itself so it is very complicated to find out which branch did not create any file: error = "continue" does not work, as well saving a workspace on error.

I thought of a solution which sounds more like a hack: always creating a dummy file in addition to the possible real ones, and then filter it out of the list of paths in a child target.

Would it be possible to allow targets that might not create any files or just empty directories?
