Zoho Flow gives the ability to track down, troubleshoot, and fix errors with the Status and Filter dropdowns in the History tab. This works well for when a "normal" Flow action registers with an error.

However, there are other times where it would be helpful for users to be able to designate a path as an error and re-run. One tangible examples is when a "null" response is returned from a Flow when it shouldn't be. I'm sure there are dozens of others.

If Flow implemented the ability to designate branches of Decision boxes as Error Branches, that would allow users to better set up error handling and more easily troubleshoot Flows.
