Given a repository $repoOwner/$repoName, find the id of an issue …

…by its `$number`.

Usually users think of "issue #10", but most GitHub GraphQL mutations refer to issues by their id, so you'll find this query quite helpful! For example, you'll need the issue id if you want to [Delete a GitHub issue](GitHubDeleteIssue).


To find the id of issue #3 on the [OneGraph GraphQL Docs Repository](#1), we could pass in the following variables:
  
  ```javascript
  {
    "repoName": "graphql-docs",
    "repoOwner": "OneGraph",
    "number": 3
  }
  ```
