Issue Summary

When adding a select filter to customFields/teams endpoint, the results will return null for  several fields that are confirmed to have non-null values

Steps to Reproduce

1. Create a default mapping for a team
2. Run a GET against the endpoint /rest/align/api/2/Connectors/1/customFields/teams
3. Note that the team has a Jira Team Value and may have a Project Key
4. Add a $select filter to the GET /rest/align/api/2/Connectors/1/customFields/teams?$select=id,jiraTeamValue,projectKey,teamId
5. Notice that the jiraTeamValue and projectKey fields are null compared to the unfiltered results

Expected Results

$select filter in API returns the same result values as the unfiltered version

Actual Results

$select filter is returning null for what should be populated fields

Workaround

Do not apply a $select filter to this endpoint
