## Summary
Add a dedicated **Errors tab** to the Right Side Panel that displays
prompt-level, node validation, and runtime execution errors in a
unified, searchable, grouped view — replacing the need to rely solely on
modal dialogs for error inspection.
## Changes
- **What**:
- **New components** (`errors/` directory):
- `TabErrors.vue` — Main error tab with search, grouping by class type,
and canvas navigation (locate node / enter subgraph).
- `ErrorNodeCard.vue` — Renders a single error card with node ID badge,
title, action buttons, and error details.
- `types.ts` — Shared type definitions (`ErrorItem`, `ErrorCardData`,
`ErrorGroup`).
- **`executionStore.ts`** — Added `PromptError` interface,
`lastPromptError` ref and `hasAnyError` computed getter. Clears
`lastPromptError` alongside existing error state on execution start and
graph clear.
- **`rightSidePanelStore.ts`** — Registered `'errors'` as a valid tab
value.
- **`app.ts`** — On prompt submission failure (`PromptExecutionError`),
stores prompt-level errors (when no node errors exist) into
`lastPromptError`. On both runtime execution error and prompt error,
deselects all nodes and opens the errors tab automatically.
- **`RightSidePanel.vue`** — Shows the `'errors'` tab (with ⚠ icon) when
errors exist and no node is selected. Routes to `TabErrors` component.
- **`TopMenuSection.vue`** — Highlights the action bar with a red border
when any error exists, using `hasAnyError`.
- **`SectionWidgets.vue`** — Detects per-node errors by matching
execution IDs to graph node IDs. Shows an error icon (⚠) and "See Error"
button that navigates to the errors tab.
- **`en/main.json`** — Added i18n keys: `errors`, `noErrors`,
`enterSubgraph`, `seeError`, `promptErrors.*`, and `errorHelp*`.
- **Testing**: 6 unit tests (`TabErrors.test.ts`) covering
prompt/node/runtime errors, search filtering, and clipboard copy.
- **Storybook**: 7 stories (`ErrorNodeCard.stories.ts`) for badge
visibility, subgraph buttons, multiple errors, runtime tracebacks, and
prompt-only errors.
- **Breaking**: None
- **Dependencies**: None — uses only existing project dependencies
(`vue-i18n`, `pinia`, `primevue`)
## Related Work
> **Note**: Upstream PR #8603 (`New bottom button and badges`)
introduced a separate `TabError.vue` (singular) that shows per-node
errors when a specific node is selected. Our `TabErrors.vue` (plural)
provides the **global error overview** — a different scope. The two tabs
coexist:
> - `'error'` (singular) → appears when a node with errors is selected →
shows only that node's errors
> - `'errors'` (plural) → appears when no node is selected and errors
exist → shows all errors grouped by class type
>
> A future consolidation of these two tabs may be desirable after design
review.
## Architecture
```
executionStore
├── lastPromptError: PromptError | null ← NEW (prompt-level errors without node IDs)
├── lastNodeErrors: Record<string, NodeError> (existing)
├── lastExecutionError: ExecutionError (existing)
└── hasAnyError: ComputedRef<boolean> ← NEW (centralized error detection)
TabErrors.vue (errors tab - global view)
├── errorGroups: ComputedRef<ErrorGroup[]> ← normalizes all 3 error sources
├── filteredGroups ← search-filtered view
├── locateNode() ← pan canvas to node
├── enterSubgraph() ← navigate into subgraph
└── ErrorNodeCard.vue ← per-node card with copy/locate actions
types.ts
├── ErrorItem { message, details?, isRuntimeError? }
├── ErrorCardData { id, title, nodeId?, errors[] }
└── ErrorGroup { title, cards[], priority }
```
## Review Focus
1. **Error normalization logic** (`TabErrors.vue` L75–150): Three
different error sources (prompt, node validation, runtime) are
normalized into a common `ErrorGroup → ErrorCardData → ErrorItem`
hierarchy. Edge cases to verify:
- Prompt errors with known vs unknown types (known types use localized
descriptions)
- Multiple errors on the same node (grouped into one card)
- Runtime errors with long tracebacks (capped height with scroll)
2. **Canvas navigation** (`TabErrors.vue` L210–250): The `locateNode`
and `enterSubgraph` functions navigate to potentially nested subgraphs.
The double `requestAnimationFrame` is required due to LiteGraph's
asynchronous subgraph switching — worth verifying this timing is
sufficient.
3. **Store getter consolidation**: `hasAnyError` replaces duplicated
logic in `TopMenuSection` and `RightSidePanel`. Confirm that the
reactive dependency chain works correctly (it depends on 3 separate
refs).
4. **Coexistence with upstream `TabError.vue`**: The singular `'error'`
tab (upstream, PR #8603) and our plural `'errors'` tab serve different
purposes but share similar naming. Consider whether a unified approach
is preferred.
## Test Results
```
✓ renders "no errors" state when store is empty
✓ renders prompt-level errors (Group title = error message)
✓ renders node validation errors grouped by class_type
✓ renders runtime execution errors from WebSocket
✓ filters errors based on search query
✓ calls copyToClipboard when copy button is clicked
Test Files 1 passed (1)
Tests 6 passed (6)
```

by [Unito](https://www.unito.io)
- "Enter Subgraph" "Show advanced inputs" and a new "show node Errors"
button now use a combined button design at the bottom of the node.
- A new "Errors" tab is added to the right side panel
- After a failed queue, the label of an invalid widget is now red.
- Badges other than price are now displayed on the bottom of the node.
- Price badge will now truncate from the first space, prioritizing the
sizing of the node title
- An indicator for the node resize handle is now displayed while mousing
over the node.
