ResponseCode.ChannelAuthSelectionRequired

Error message

ChannelAuthSelectionRequired

What it means

Thrown in AuthService.saveSelectedAccountsForUser when the submitted selectedAccounts array is empty. Persisting the user's chosen second-level accounts requires at least one account identity ({ platformUid, account? }); an empty submission means nothing was selected.

Solutions

1. Enforce at least one selection in the UI (disable submit until a checkbox is ticked) and validate client-side before POSTing.
2. Reject empty arrays at the DTO boundary with a Zod min-length constraint so callers get a clear 400-style message.
3. Check the frontend form serialization — ensure the accounts field is populated from the selection checkboxes.
4. If the user legitimately wants to select none, cancel the flow instead of submitting an empty selection.

Example fix

// before: DTO allows empty array
accounts: z.array(selectedAccountSchema)

// after: require at least one selection
accounts: z.array(selectedAccountSchema).min(1)

function canSubmitSelection(selected: SelectedAccountIdentity[]): boolean {
  return Array.isArray(selected) && selected.length > 0
}
if (!canSubmitSelection(collectedSelections)) {
  alert('Select at least one account')
  return
}

function hasSelections(v: unknown): v is SelectedAccountIdentity[] {
  return Array.isArray(v) && v.length > 0 && v.every(i => typeof (i as any).platformUid === 'string')
}

try {
  await submitSelections(selected)
}
catch (e) {
  if (getErrorCode(e) === ResponseCode.ChannelAuthSelectionRequired) {
    showError('Please select at least one account before continuing')
  }
}

When it happens

Trigger: saveSelectedAccountsForUser (via connectSelectableAccounts / connectSelectedAccountsForUser, e.g. POST /accounts/auth/selections) with body.accounts = [] — an empty selection form, a frontend bug sending no accounts, or an API caller omitting the accounts list.

Common situations: User submits the account-selection page without ticking any checkbox; frontend not mapping the checkbox values into the request body; DTO accepting an empty array because the schema only validates item shape, not min length; scripted calls to the endpoint with an empty payload.
