Error message

--subject must be 200 characters or fewer

What it means

buildCreateMessagePayload enforces a maximum subject length of 200 characters (after normalization). Subjects exceeding that limit would be rejected by the Sales Navigator API, so the library fails fast with ArgumentError.

Solutions

1. Shorten the subject to 200 characters or fewer.
2. Collapse excessive whitespace before sending (the library normalizes nbsp, so pre-trim your template).
3. Truncate programmatically: subject.slice(0, 200) with ellipsis if acceptable.

Example fix

// before
const subject = veryLongTemplate;
// after
const subject = veryLongTemplate.length > 200 ? veryLongTemplate.slice(0, 197) + '...' : veryLongTemplate;

if ([...String(subject).replace(/[\u00a0\u202f]/g,' ')].length > 200) subject = subject.slice(0, 200);

try { await sendMessage({ subject, body }); } catch (e) { if (/subject must be 200 characters or fewer/.test(e.message)) { subject = subject.slice(0, 200); /* retry */ } else throw e; }

When it happens

Trigger: cleanSubject.length > 200 — a subject longer than 200 characters after whitespace normalization.

Common situations: Auto-generated or templated subjects (long job titles, merged fields) exceeding the cap; pasted rich text with extra non-breaking spaces inflating length.
