DatabaseBlockError

Error message

View ${viewId} not found

What it means

Thrown by DataViewRootUILogic.createDataViewUILogic (blocksuite/affine/data-view/src/core/data-view.ts:64-71) when viewManager.viewGet(viewId) returns undefined. The data-view widget builds a per-view UI logic for every id in dataSource.viewDataList$; if the view manager cannot resolve an id to a view meta (renderer, name), database-block rendering aborts with this DatabaseBlockError. It almost always means a dangling view id: the id list and the actual view storage are out of sync.

Solutions

1. Check dataSource.viewManager.viewGet(viewId) before rendering and skip/prune the stale id instead of constructing the UI logic
2. Delete the stale entry from the block's view list (viewDelete or equivalent) so viewDataList$ and the view manager stay in sync
3. When restoring old snapshots, migrate first: drop view entries whose id no longer resolves, or rebuild a default view
4. Wrap mount/render in try-catch for BlockSuiteError with code DatabaseBlockError and fall back to the first resolvable view

Example fix

// before
const logic = this.createDataViewUILogic(viewData.id); // throws 'View xxx not found'

// after
const view = this.viewManager.viewGet(viewData.id);
if (!view) {
  this.viewManager.viewDelete(viewData.id); // prune the dangling id
  return null;
}

const isViewIdResolvable = (dataSource: DataSource, viewId: string): boolean =>
  !!dataSource.viewManager.viewGet(viewId);

// prune before rendering
const validViewData = dataSource.viewDataList$.value.filter(v =>
  isViewIdResolvable(dataSource, v.id)
);

function isResolvedView(view: SingleView | undefined): view is SingleView {
  return view !== undefined;
}

try {
  const logic = this.createDataViewUILogic(viewId);
} catch (e) {
  if (e instanceof BlockSuiteError && e.code === BlockSuiteError.ErrorCode.DatabaseBlockError) {
    // stale view id: remove it from the view list and re-render, do not crash the editor
    this.viewManager.viewDelete(viewId);
    return;
  }
  throw e;
}

When it happens

Trigger: A view is deleted while the views$ computed is mid-update (reactive race), so viewDataList$ still holds a removed id; restoring a database-block snapshot whose views array references a view id that no longer exists; calling viewManager.viewGet / mounting the data-view with a stale or hand-crafted id from untrusted JSON.

Common situations: Rapid view deletion during a reactive re-render; corrupted or hand-edited database block JSON; collaborative editing where a remote peer deletes a view the local client is rendering; block migrations that regenerate view ids without pruning references.
