Error message

${resp.data}

What it means

cellsynt.js:29-31. Cellsynt returns an error as a plain-text body starting with 'Error:'. The provider strips the 'Error:' prefix and throws the remaining text, which is the human-readable Cellsynt failure reason (e.g. 'Invalid destination', 'Wrong username or password').

Solutions

1. Read the stripped message verbatim — it names the Cellsynt reason (auth, destination, credits).
2. Verify username/password against the Cellsynt customer portal.
3. Format destination as international number without leading + or 00 per Cellsynt docs.
4. Check account balance and originator configuration.

// Pre-validate Cellsynt credential + destination format
function cellsyntPreflight(notification) {
    if (!notification.cellsyntLogin || !notification.cellsyntPassword) throw new Error('Cellsynt credentials missing');
    if (!/^\d{6,15}$/.test(notification.cellsyntDestination)) throw new Error('Cellsynt destination must be intl digits');
}

function isCellsyntOkBody(s) { return typeof s === 'string' && /^<\?xml/.test(s) && /<status>OK<\/status>/.test(s); }

try { await provider.send(...); }
catch (e) {
    const m = e.message;
    if (/auth|username|password/i.test(m)) log.error('Cellsynt auth — fix credentials');
    else if (/credit|balance/i.test(m)) heartbeat.status = PENDING;
}

When it happens

Trigger: Wrong username/password, invalid destination number format, insufficient credits, disallowed originator value, or destination on a blocked operator route.

Common situations: Credentials mismatched; destination not in the E.164 international format Cellsynt expects; originator alphanumeric string exceeds length limits; account out of credits.
