Hello!
The error message you’re seeing, “Error executing workflow with item at index 0 – Workflow does not exist”, usually means that the Execute Workflow node is trying to run a workflow that either no longer exists, has been renamed or deleted, or perhaps the reference to it has become outdated.
From your screenshot, I can also see the warning that the node is “out of date.” This typically happens when a node has been copied, imported from another project, or was created before an internal update. As a result, the workflow ID it’s referencing may no longer be valid or correctly mapped in your current environment.
