I noticed that the Import* from diffprep & Compute* from diffcalcv3 had non-zero exit codes (e.g. echo $?) when they completed. They ran fine locally, but when running in docker images (from latest ubuntu:18.04), they would exit the image because of this. Is there any consideration of letting the exit code be non-zero? Any insight would be appreciated.
Yes. This is unfortunately the case.
Most of these are already corrected but will correct the rest of them very soon.
