Error message

view not found

What it means

Sentinel ErrViewNotFound — the most frequently thrown AV error. Returned when a requested view id is absent from the AV's Views list: GetFirstView returns it when there are no views at all; parseAttributeViewByPathInBox returns it when the AV JSON file does not exist; and many model-layer operations return it when the operation targets a view id not present in the loaded AV.

Solutions

  1. Refresh the AV's view list (GET /api/av/getAttributeView) and use a current view id.
  2. If the AV has no views, create one before issuing view-scoped operations.
  3. Handle ErrViewNotFound in the client by reloading the database block rather than retrying the stale op.
  4. Confirm the AV file exists (see error 90) when the missing-file overload is suspected.

Example fix

// before
op := &av.Operation{Action: "setview", id: lastViewID}
err := model.UpdateAttributeView(op)   // stale lastViewID -> view not found

// after: reload and use a live view id
attrView, _ := av.ParseAttributeView(avID)
viewID := attrView.Views[0].ID
op := &av.Operation{Action: "setview", id: viewID}
Defensive patterns

Strategy: try-catch

Try / catch

view, err := getRenderAttributeViewView(attrView, viewID, "", "", false)
if errors.Is(err, av.ErrViewNotFound) {
    // reload the database block and pick a live view; do not retry the stale id
    attrView, _ = av.ParseAttributeView(avID)
    view, err = attrView.GetFirstView()
}

Prevention

When it happens

Trigger: Calling a database operation (setfilter, setsort, setview, getview, render) with a view id that was deleted, never existed, or belongs to a different AV. Also when rendering a brand-new AV that has had no view created yet, or when the AV file itself is missing.

Common situations: Client holds stale state after another tab/session deleted or switched the view; a plugin reused a hardcoded view id; race between view deletion and an in-flight operation; AV file removed but block still references it.
