Failed to fetch team

Error message

Failed to fetch team

What it means

Thrown by TeamAPI.getTeam when GET /teams/{id}?user_id=... returns falsy status. The standard cause is a team id that does not exist or is owned by a different user_id — the backend's ownership check answers through the status envelope.

Solutions

1. Check the id against listTeams(userId) output before loading it
2. Clear stale selected-team state on user change or on 404-flavored messages
3. Read data.message for the backend wording
4. If the list is empty, re-create or re-import the team rather than retrying the id

Example fix

// before
const team = await teamAPI.getTeam(teamId, userId);
// after
const teams = await teamAPI.listTeams(userId);
const team = teams.find(t => t.id === teamId);
if (!team) throw new Error(`Team ${teamId} not found for this user`);

const teams = await teamAPI.listTeams(userId);
if (!teams.some(t => t.id === teamId)) {
  throw new Error(`Team ${teamId} not found for this user`);
}

function isTeamEnvelope(x: unknown): x is { status: true; data: Team } {
  return !!x && (x as any).status === true && !!(x as any).data?.id;
}

try {
  return await teamAPI.getTeam(teamId, userId);
} catch (e) {
  if (/not found|does not exist/i.test(String(e))) navigateToTeamsList();
  throw e;
}

When it happens

Trigger: GET /teams/{teamId}?user_id=X for a deleted team, another user's team, or after a DB reset wiped team rows while the UI kept a stale id.

Common situations: Gallery/team link opened after the team was deleted, user switch without clearing selected team state, backend DB recreated (teams gone, frontend state persists).
