This problem analyzer helps you deploy changes to Flow Definitions.
Note: With the release of Winter '19 (v44 of the metadata API), Salesforce have made major changes to how Flow and Flow Definitions are handled by the metadata API. See our support doc on the changes and how they affect you.
What triggers this analyzer?
If you include Flow Definition deletions in your deployment, this problem analyzer will be triggered.
What problem in it solving?
It isn't possible to delete flow definitions via the metadata API. If you try, your deployment will fail with the error
insufficient access rights on cross-reference id.
How does it work?
Gearset will remove these deletions from your deployment. You'll need to delete the flow itself to delete the flow definition.
