Issue

When moving a flow from one instance of Hyperscience to another (e.g., from a development instance to production), a “Release with given UUID does not exist” error could appear in the Flow Studio for the imported flow.

Affected versions

V31 and later

Affected configurations

All configurations

Cause

The imported flow is looking for a release with the UUID from the original instance.

Solution / Workaround

1. Export the release from the original environment.
   • For more information, see “Exporting a Release” for your version of Hyperscience ( v38 | v39 | v40 | v41 | v42 | v43).
2. Import the release into the destination environment.
   • To learn more, see “Adding a New Release” for your version of Hyperscience ( v38 | v39 | v40 | v41 | v42 | v43).
3. (v32 and later) Assign the release to the flow in the destination environment.
