Issue not found

Error message

Issue not found

What it means

Thrown by fetchIssueWithIdentifier in the web issue store when retrieveWithIdentifier returns a falsy issue, or one missing id/project_id. The lookup uses workspaceSlug + project_identifier + sequence_id (e.g. 'PLAN-123'); a miss means no issue matches that identifier triple.

Solutions

1. Confirm the identifier triple is correct and current (project identifier changes when a project is renamed).
2. Verify the user has access to the project and the issue is not archived/deleted.
3. Inspect the network response from retrieveWithIdentifier — a 404 vs 403 vs 200-with-empty-body points to different root causes.
4. Handle the thrown error in the route to show a 'not found' page instead of crashing the workspace view.

Example fix

// before: throws and propagates upward
if (!issue || !projectId || !issueId) throw new Error("Issue not found");
// after: branch on the API outcome and surface a typed result
if (!issue || !projectId || !issueId) {
  return { status: 'not-found' } as const;
}

// Validate identifier shape before calling
const seqRe = /^-?\d+$/;
if (!workspaceSlug || !project_identifier || !seqRe.test(sequence_id)) {
  showNotFound();
  return;
}

const isResolvedIssue = (i: unknown): i is { id: string; project_id: string } =>
  typeof i === 'object' && i !== null &&
  typeof (i as any).id === 'string' &&
  typeof (i as any).project_id === 'string';

try { await fetchIssueWithIdentifier(workspaceSlug, project_identifier, sequence_id); }
catch (e) { renderNotFoundPage(); }

When it happens

Trigger: Navigating to an issue URL whose identifier does not exist (typo in sequence/identifier), the issue was deleted, the project was moved/renamed so the identifier changed, the user lacks access (some backends return 404 instead of 403 to avoid leaking existence), or the API returned a partial/malformed payload missing id/project_id.

Common situations: Old bookmarked link to a deleted issue; pasting a truncated identifier; permission changes that removed the user from the project; cross-workspace link opened by a user without access.
