How to use the jira.get_issue_json function in jira

def generate_folder(tickets_json, project_id: str, jira_key: str, extension) -> str:
    summary = jira.get_issue_json(tickets_json, jira_key)['fields']['summary']
    sections = list(map(lambda s: s.strip().title(), summary.split(':')))
    sections = sections[:-1]  # remove last bit of summary
    sections = list(filter(lambda s: len(s) < 50, sections))
    if extension is not None:
        sections = extension(jira.get_issue_json(tickets_json, jira_key), sections)
    sections.insert(0, project_id)
    return '/'.join(sections) + '/'
