ErrViewNotFound

ErrViewNotFound

Error message

view not found

What it means

ErrViewNotFound means the requested view (tab within an attribute view) could not be located. It is returned when the .av file does not exist on disk (parseAttributeViewByPathInBoxWithOptions), when the AV has no usable first view (GetFirstView), and when an operation references a view ID that isn't present (syncAttrViewTableColWidth, foldAttrViewGroups, getAttrViewOperationView). The API layer maps it to a 'viewNotFound' data payload for the frontend.

Solutions

1. Re-fetch the AV's current view list (RenderAttributeView) and use the returned active view ID instead of a cached one
2. Fall back to GetFirstView / the default view when the stored view ID is absent
3. Verify the .av file exists in storage/av for the given notebook
4. Handle the API payload {"error":"viewNotFound"} in frontend code by reloading the database view

Example fix

// before
err := setAttrViewSort(avID, staleViewID, sorts) // ErrViewNotFound
// after
attrView, _ := av.ParseAttributeView(avID)
viewID := staleViewID
if _, err := attrView.GetView(viewID); errors.Is(err, av.ErrViewNotFound) {
    view, _ := attrView.GetFirstView()
    viewID = view.ID
}
err := setAttrViewSort(avID, viewID, sorts)

attrView, err := av.ParseAttributeView(avID)
if err != nil { return err }
for _, v := range attrView.Views {
    if v.ID == viewID { return nil } // requested view exists, safe to proceed
}
return errors.New("view no longer exists; use GetFirstView fallback")

func viewExists(attrView *av.AttributeView, viewID string) bool {
    _, err := attrView.GetView(viewID)
    return !errors.Is(err, av.ErrViewNotFound)
}

err := doViewOp(avID, viewID)
if errors.Is(err, av.ErrViewNotFound) {
    if first, ferr := attrView.GetFirstView(); ferr == nil {
        err = doViewOp(avID, first.ID) // fall back to the first view
    }
}

When it happens

Trigger: Referencing a stale/deleted viewID in attribute-view operations (sort/filter/fold/column width) against an AV whose JSON no longer contains that view; the .av file missing on disk; operating on an AV with zero views.

Common situations: A plugin cached a view ID and the view was later deleted or replaced; sync merged AVs and dropped a view; the frontend sent operations for a view from before a database re-creation; a notebook moved without its storage/av directory.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
