Start with the reported stack trace at node_modules/passport-2fa-totp/lib/strategy.js:119 and review how passport.use('login') configures TwoFAStartegy. Reproduce the TypeError and ERR_HTTP_HEADERS_SENT behavior with the shown configuration; done requires identifying whether the failure is in Passport or the passport-2fa-totp integration and documenting a reproducible case.
