/**
* Get the issue type hierarchy for a next-gen project.

The issue type hierarchy for a project consists of:

 *  *Epic* at level 1 (optional).
 *  One or more issue types at level 0 such as *Story*, *Task*, or *Bug*. Where the issue type *Epic* is defined, these issue types are used to break down the content of an epic.
 *  *Subtask* at level -1 (optional). This issue type enables level 0 issue types to be broken down into components. Issues based on a level -1 issue type must have a parent issue.

**[Permissions](#permissions) required:** *Browse projects* [project permission](https://confluence.atlassian.com/x/yodKLg) for the project.
* Documentation: https://developer.atlassian.com/cloud/jira/platform/rest/v3/#api-rest-api-3-project-projectId-hierarchy-get
* @param options Request options.
* @deprecated
