In an ESM project, calling TelnyxWebhook.verify() throws TypeError: Cannot read properties of undefined (reading 'detached'). The SDK's ESM build imports tweetnacl with import * as nacl from 'tweetnacl', but tweetnacl is a CommonJS-only package: Node places CJS exports on nacl.default, so nacl.sign is undefined and nacl.sign.detached.verify(...) crashes. The same code works in CommonJS projects.

This was an SDK ESM/CJS interop bug with the tweetnacl namespace import. Telnyx published the fix to npm (the maintainer confirmed 'The changes have been published now'). Upgrade telnyx to the latest version and TelnyxWebhook.verify() works in ESM projects. Source: https://github.com/team-telnyx/telnyx-node/issues/302
