Issue Summary

The endpoints rest/api/2/search and rest/api/3/search return an internal server error if you add the following to the call "expand":["changelog"],.

Steps to Reproduce

• Perform a call as the following:

  curl --request POST \
    --url 'https://<Jira_url>.atlassian.net/rest/api/3/search' \
    --user '<EMAIL>:<API_TOKEN>' \
    --header 'Accept: application/json' \
    --header 'Content-Type: application/json' \
    --data '{
    "jql": "key = SPLAN-79",
    "maxResults": 15,
    "fieldsByKeys": false,
    "fields": [
      "summary",
      "project",
      "issuetype",
      "fixVersions",
      "versions",
      "reporter",
      "assignee",
      "priority",
      "status",
      "resolution",
      "created",
      "updated",
      "duedate",
      "resolutiondate",
      "timetracking",
      "timeoriginalestimate",
      "timeestimate",
      "parent",
      "security",
      "customfield_10014",
      "customfield_10011",
      "customfield_10012",
      "customfield_10020"
      ],
    "expand":["changelog"],
    "startAt": 0
  }'
  

Expected Results

The call works, returning all the data from that issue.

Actual Results

An internal server error is returned.

Workaround

Remove "expand":["changelog"] from the call.

In case you need the changelog, use the endpoint rest/api/3/issue/<issueIdOrKey>/changelog.
