res.error || "Failed to save flow"

Error message

res.error || "Failed to save flow"

What it means

Frontend guard in AgentFlows.saveFlow: the POST to /agent-flows/save returned a non-ok HTTP status, meaning the backend rejected the flow save (e.g. validation failure or server error); the server-provided error is used when present, otherwise the generic 'Failed to save flow' text.

Solutions

1. Check the server response error for details and correct the flow definition.
2. Verify the flow JSON schema and required fields before saving.
3. Retry after fixing validation errors reported by the server.

When it happens

Trigger: Thrown when the agent flow save API call returns an error.

Common situations: Invalid flow definition, missing required fields, or server-side validation failure.
