If @suprsend/node-sdk 1.15.0 crashes on startup with a missing request_json/workflow.json module error, do not debug your own code: upgrade to v1.15.1. That release had a broken build script interaction with the newer Babel CLI. Pinning to 1.14.0 also works as a stopgap, but 1.15.1 is the fixed release.

Context: GitHub issue suprsend/suprsend-node-sdk#72 (closed): Version 1.15.0 of the SDK crashed on Node 18 at require time with "Cannot find module './request_json/workflow.json'". A community member traced the root cause: PR #68 had bumped the Babel CLI, and the newer Babel copies non-JS files into dist by default, so the build's mkdir step for dist/request_json collided with the directory Babel had already created. A maintainer released v1.15.1 with the fix.
