What causes "Conf.Language(30) + " " + err.Error()" in siyuan-note/siyuan?

Read the full error message after the prefix to identify the underlying cause.

Conf.Language(30) + " " + err.Error()

Error message

Conf.Language(30) + " " + err.Error()

What it means

GetCloudSpace wraps getCloudSpace and prefixes any underlying failure with the localized string for i18n key 30 ("Failed to obtain cloud info"). The final error message is "<localized prefix> <underlying error>". The real cause is always in the appended err.Error() — typically network failure, auth expiry, or a cloud API error.

Solutions

Read the full error message after the prefix to identify the underlying cause.
Check network connectivity and proxy/firewall settings for the cloud endpoint.
Log out and back in at Settings - Account & Sync - Account to refresh the token.
Retry later if the cloud service is temporarily unavailable.

Example fix

// before
const resp = await fetchPost('/api/repo/getCloudSpace', {});
// after
const resp = await fetchPost('/api/repo/getCloudSpace', {});
if (resp.code !== 0 && resp.msg.includes('Failed to obtain cloud info')) {
  // inspect resp.msg tail for the underlying cause; check network, re-login
  await fetchPost('/api/account/logout', {});
  // prompt user to log in again
}

Defensive patterns

Strategy: try-catch

Validate before calling

if (!navigator.onLine) {
  throw new Error('Cannot get cloud space while offline');
}

Try / catch

try {
  const resp = await fetchPost('/api/repo/getCloudSpace', {});
} catch (e) {
  // message = localized prefix + underlying cause; parse tail after 'Failed to obtain cloud info'
  const cause = e.message.replace(/^.*?Failed to obtain cloud info\s*/, '');
  if (/network|timeout|dial/i.test(cause)) showNetworkHelp();
  else if (/auth|token|login/i.test(cause)) promptRelogin();
}

Prevention

Check connectivity before querying cloud space in scripts.
Re-authenticate after long idle periods to avoid expired-token failures.
Always inspect the appended underlying error, not just the localized prefix.
Handle cloud maintenance windows with retry/backoff.

When it happens

Trigger: POST /api/repo/getCloudSpace (opening the cloud storage dialog or checking cloud usage) when the request to the cloud service fails: network outage, expired/invalid session token, subscription issues, or cloud-side 5xx.

Common situations: Offline or behind a proxy/firewall blocking the cloud endpoint; session token expired after long idle; cloud service maintenance; DNS failures on restricted networks.
