Duplication could also indicate a typo or other mistake; this rule alerts you if such a situation arises. ## Configuration | Option | Type | Description | | --- | --- | --- | | severity | string | Possible values: `off`, `warn`, `error`. Default `off`. | An example configuration: ```yaml rules: workflowId-unique: error ``` ## Examples Given the following configuration: ```yaml rules: workflowId-unique: error ``` Example of a **correct** `workflows` list: ```yaml workflows: - workflowId: get-museum-hours steps: - stepId: get-museum-hours operationId: museum-api.getMuseumHours successCriteria: - condition: $statusCode == 200 - workflowId: get-museum-hours-routine steps: - stepId: get-museum-hours operationId: museum-api.getMuseumHours successCriteria: - condition: $statusCode == 200 ``` ## Resources - [Rule source](https://github.com/Redocly/redocly-cli/blob/main/packages/core/src/rules/arazzo/workflowId-unique.ts)
