The documentation on https://docs.atlassian.com/jira/REST/latest/#api/2/board-getBoard is confusing in the way that it is using a SCRUM project key example and the endpoing is only for JIRA Core boards.

The confusion is caused by having the endpoint named board

Please consider:

• adding a comment to clarify this difference and avoid confusion with the Agile Boards https://docs.atlassian.com/greenhopper/REST/cloud/
• changing the example to a CORE project instead of SCRUM
• create a new type of error that mentions that the endpoint is being used to retrieve data from a JIRA Agile board instead of Core board. (see confusion caused on JRA-60195 )
