Hi Rob, thank you for your answer. Yes, I have first checked if the status is "Finished". My test workflow is a very simple "Say Hello" with one input, a string concatenation and one output, so finishing very fast. I also tried other workflows but always end up with the same error message.
I also would exclude any problems with write permissions, because I am able to create a new user defined directory in the working directory of that workflow (i.e. with makeRunDirectory). Or could this still be a problem? Regards, Nina ________________________________________ Von: Robert Haines [[email protected]] Gesendet: Dienstag, 7.

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.
