 | failOnThreshold           | The `severityThreshold` parameter is used to control the interaction with the Snyk CLI and reporting vulnerabilities. The `failOnThreshold` gives you additional control over build failure behaviour. For example, with `failOnIssues` set to `true` and `failOnThreshold` to `critical`, all issues would be reported on but _only_ critical issues would cause a build failure.
