The same build artifacts is gets download for other staged like dev in same release pipeline, but not working with QA stage. What value cannot be null? there is a built artifact there in the system I can see it and the release has a valid link to it.

Answer 1

The issue can be resolved by upgrading the version from 1.189.0 to 2.0.0 After upgrading the version if you still face the issue try this

1. Open Download Pipeline Artifact
2. check the Destination Directory property
3. If it is reset to $(System.ArtifactsDirectory) change to the specific path which is given by you.
4. If not check if there is any data that should be cleared in the artifact directory folder. Because the artifact directory should be empty before downloading.
