Webpack failure TypeError: hexoid is not a function

TL;DR

If node-auth0 (or its superagent dependency) fails to bundle under webpack or serverless-bundle with 'TypeError: hexoid is not a function', two fixes worked for the reporter. One: disable Formidable in the bundle via serverless.yml: custom: bundle: aliases: - formidable: false.

Steps

1. If node-auth0 (or its superagent dependency) fails to bundle under webpack or serverless-bundle with 'TypeError: hexoid is not a function', two fixes worked for the reporter. One: disable Formidable in the bundle via serverless.yml: custom: bundle: aliases: - formidable: false. Two: downgrade superagent from v7 to v6. superagent usually comes in as a transitive dependency, so pin it with yarn resolutions: { "resolutions": { "superagent": "6.x" } }. Either one cleared the build.
