Response Headers return null

[YY1]

Hi, anyone knows why the headers return null?

let response = undefined;

    try{
      response = await api 
        .asUser()
        .requestJira(route `/rest/agile/1.0/sprint/${SprintId}/issue`);
      if (response.status == 429){
        console.log(`fetchAllIssuesforSprint-Rate Limiting: ${response.headers.get('Retry-After')} || ${response.headers.get('X-RateLimit-Reset')}`);
      }
      const data = await response.json();
      return data;
    }catch (error) {
      if (error instanceof SyntaxError) {
        console.log(`fetchAllIssuesforSprint-AtlTraceID: ${response.headers.get('Atl-Traceid')} || X-Arequestid: ${response.headers.get('X-Arequestid')}`);
        console.error('SyntaxError in fetchAllIssuesforSprint:', error.message);
      } else {
        throw error;
      }
    }
