Are you sure that the workflow run has finished before you try to get
the outputs? There is no guarantee that any outputs will be present
until the run has completely finished. Some partial outputs *may* appear
before the run has finished but they will appear at random times,
depending on the workflow, and will be in a state of flux until it is
finished.
To guarantee the presence of the outputs, please check that the run is
finished before trying to read the outputs.
Best wishes,
Rob
